add i2c module

Initial migration to IDFv5.0 Plenty of dependency adjustments, printf format specificier updates, FreeRTOS type and macro name modernisation, not to mention API changes. Still plenty of legacy/deprecated drivers in use which will need updating. The following features have been removed due to no longer being available from the IDF: - ADC hall effect sensor reading - Configuration of SD SPI host via sdmmc module (now must be done first via the spimaster module) - FAT partition selection on external SD cards; only the first FAT partition is supported by the IDF now On the other hand, the eth module now supports the following new chipsets: - KSZ8001 - KSZ8021 - KSZ8031 - KSZ8051 - KSZ8061 - KSZ8091 - Possibly additional models in the LAN87xx series (the IDF docs aren't clear on precisely which models are handled) Further, the sdmmc module is now available on the ESP32-S3 as well.

Switch to IDF-provided VFS and standard `io` module. The IDF-provided VFS resolves several issues: - The IDF components having a different view of the (virtual) file system compared to the Lua environment. - RTOS task/thread safety. Our legacy VFS was only ever safe to use from the LVM thread, which limited its usability. Upgrading it would have effectively required a reimplementation of the IDF VFS, which would have been a bigger task with larger on-going maintenance issues. - We're no longer needing to maintain our own SPIFFS component. - We're no longer needing to maintain our own FATFS component. - The legacy of the 8266's lack of standard C interface to the file system is no longer holding us back, meaning that we can use the standard Lua `io` module rather than the cobbled-together swiss army knife also known as the file module. Of course, the downside is that we'll either have to declare a backwards breakage in regard to the file module, or provide a Lua shim for the old functions, where applicable. Also included is some necessary integer type fixups in unrelated code, which apparently had depended on some non-standard types in either the SPIFFS or FATFS headers. A memory leak issue in the sdmmc module was also found and fixed while said module got switched over to the Espressif VFS. Module documentation has been updated to match the new reality (and I discovered in some places it wasn't even matching the old reality).
