* maint(build): remove legacy GNU Make build system support

* maint(example): move the example so that component manager finds it

* maint(example): specify component dependency

* maint(build): clean up legacy 'register_component' usage

* maint(build): specify more fields in component manifest

* doc(readme): simplify installation instructions

See https://github.com/espressif/esp32-camera/issues/596

* maint(ci): remove tests for EOL versions (v4.1, v4.2)

* fix(build): add missing transitive dependency on driver component

- Check if we have remaining ticks before going for math and calling cam_take recursively

* Fails with ESP32 (standard) and ESP-IDF v5.2

With IDF 5.2 master it works with esp32-s3 but fails with esp32 standard, and has two problems:

First is that when compiling it does not find the function: ets_delay_us'.
implicit declaration of function 'ets_delay_us';

Second that it fails to initialize xlock.
camera_xclk: ledc_timer_config failed, rc=103

The solution is to add #define ets_delay_us esp_rom_delay_us when the idf version is greater than 5 and initialize the variable timer_conf.deconfigure = false;

* Extend s/w jpeg decoder functions for chips missing rom tjpgd

Also, disabled camera_init and capture from example for chips not
supporting camera

Since `gpio_install_isr_service()` is called when initializing the
camera, but on de-initiazlization the ISR service is not uninstalled.
This causes an error `gpio_install_isr_service(410): GPIO isr service
already installed` when the camera is re-initialized.

* Fix: Make esp32-camera function prototypes strict

This is required for pedantic builds with
-Wstrict-prototypes flag

* ci: Enable pedantic example build

* ov7670: fix ov7670_frame_control()

Last value of array (VREF) was overwritten by end marker

* OV7670: Adapt QQVGA VSTART value to remove bar on top

Remove empty bar at the top of the frame. This is more visible on
OV7675, but also present on OV7670

fix: fix bad macro definition on cam stack size

Feature/support sccb handle 16bit val

fix: heap corruption caused by dma_buffer in cam_deinit()

fix: fix description of resolution in docs and examples

feat: add SC031GS camera sensor support

don't reset LEDC channel if it wasn't used by camera

feat: change sccb APIs for sharing i2c port with other devices

fix bug when config->pin_xclk = -1 target esp32s3

Added support for 8-bit grayscale output to fmt2bmp() for frame2bmp()

Change the fb buffer as 16 bytes aligned
