platformio requires changes to the examples

[nickolay]

First:

LilyGo-EPD47/examples/button$ pio run --list-targets
InvalidEnvNameError: Invalid environment name 't5-4.7'. The name can contain alphanumeric, underscore, and hyphen characters (a-z, 0-9, -, _)

This is due to platformio/platformio-core@269d5e0

Second (you need to prune ~/.platformio to see this):
UnknownPackageError: Could not find the package with 'espressif/toolchain-riscv32-esp @ 8.4.0+2021r2-patch3' requirements for your system 'darwin_x86_64'

This is probably caused by pinning an old arduino-esp32 version

LilyGo-EPD47/examples/button/platformio.ini

Line 20 in f6a4fab

platform_packages = framework-arduinoespressif32@https://github.com/espressif/arduino-esp32.git#2.0.5

This was reported to me in nickolay/esphome-lilygo-t547plus#6
