v8.1.0 - WAV Files, Sensors, and Bugfixes

Features

• Audio Files: Reworked WavPlayer, added helpful utilies for working with WAV files (WavParser, FileTable), and added examples for demonstrating their usage.
• SDMMC: HAL_SD_ErrorCallback is now being handled to help with error handling
  • note: this may cause things that would previously stall indefinitely to now cause an error. Often, the error will occur in f_sync() or f_close() since that is where the disk i/o tends to occur. The SDMMC_HelloWorld example has been updated to better handle these errors.
• MPR121: Added demonstration program using MPR121 to examples.

Bug Fixes

• SDMMC: fix an issue where status flags were optimized out, resulting in very long while loops
• CMake: The platform definition for the new FileReader in CMake is now properly set up for use in targets outside of libDaisy.
• ICM20948: Fixed an incorrect number of arguments on call to ReadExternalRegister.
• MPR121: Fixed i2c i/o issues that led to problems reading correct data from the sensor.
• version: The version.h hasn't been updated since v4.0.0 -- it has now been updated to the current version.

Bootloader

• Update to v6.4. This version resolves issues related to i/o timeouts that could occur after programming devices hundreds/thousands of times with larger binary files.
