Exposing this method makes it easier to integrate non-espressif USB-based projects (e.g. led/modifiers examples from USB Host Shield 2.0)

Summary

The M5Core2 and the very similar M5Tough have 40 digital pins

See reference here: https://docs.m5stack.com/en/core/core2 as well as the constant declarations in the bottom part of the file.

Impact

Without this, Code that needs the total number of pins (e.g. firmata) doesn't show the higher pin numbers correctly.

Sometimes you dont need the full 3M but want OTA instead

Summary

Touch Sensor refactoring to be based on IDF 4.4.
Adds support to ESP32S2 and future ESP32S3.

Adds some new APIs:

For all chips:

void touchAttachInterruptArg(uint8_t pin, void (*userFunc)(void*), void *arg, uint32_t threshold);
This function allows the user to add and pass a void* parameter to the ISR user callback.

void touchDetachInterrupt(uint8_t pin);
This function detaches ISR call back for the touch pad pin.

Only ESP32 chip

void touchInterruptSetThresholdDirection(bool mustbeLower);
This function allows the user to set if the ISR callback will be activated when the touch sensor readings are lower or higher than the threshold defined. See example TouchButton.ino.

Only ESP32-S2 and ESP32-S3 chips

bool touchInterruptGetLastStatus(uint8_t pin);
This function reports if the touch pad pin is touched or untouched. It can be used with ISR to identify when it is touched and untouched (released). See example TouchButtonV2.ino.

Impact

None. ll original APIs and examples now run on ESP32 and ESP32-S2.

If board has no PSRAM, we need to set the framebuffer location to DRAM:
config.fb_location = CAMERA_FB_IN_DRAM;

* Unneccesary Operation Removed

(A) extra operation not needed and incorrect:
      wrong by 0.5 but happens to be thrown out

     ( delta * dividend + (divisor / 2) ) / divisor

        delta * dividend     divisor
    = ---------------- + -----------
        divisor                    2 * divisor

    = delta * dividend / divisor + 1/2

(B) check first before doing other computations

(C) changed to rise/run, easier for future maintainer
      since it's closer to equation of a line

(D) before: mult, shift, add, div, add
      now: mult, div, add

(E) error message easier to trace where thrown

* Update WMath.cpp

forgot to change variable name

* Docs cleanup and version updated to 2.0.2

* Removed issue template information

* Removed issue template file

* Added referecnces for the issue and feature request form

CaptivePortal.ino example did randomly crash for me ... so I start investigate ;-)

I found with wireshark a possibility to trigger the crash on demand is:

The problem was that QNameLength is a signed byte and therefore its not possible to count up to 255. Additionally we need 256 bytes for the QName string to accommodate for the zero termination.

The reason behind this refactoring is that all of the sketch related functions can (and will) be used for other purposes.

Build in the sketch directory: This will make it easy to handle artifacts after the build.
Separate sketch related functions from IDE installation script. This is the main commit.
Create a separate job for the Cmake check. This check was part of one of the Linux build. I believe that it's not the best place for such a check.
Checking for the skip landmarks and validity of the the sketch directory were already done by count_sketches.

With LittleFS the `fs.exists(path)` returns true also on folders. A `isDirectory()` call is required to set _isFile to false on directories.
This enables serving all files from a folder like : `server->serveStatic("/", LittleFS, "/", cacheHeader.c_str());
        File f = fs.open(path);
        _isFile = (f && (! f.isDirectory()));

Allow a user to disable the HTTPCLIENT_1_1_COMPATIBLE flag from the command line, or whichever means available.
