Upload protocol "custom" still looks for AVRdude

[bradanlane]

platformio.ini has the following:

upload_protocol = custom
upload_port = COM3
upload_speed = 115200
upload_command = pymcuprog write -t uart -d attiny1616 -u $UPLOAD_PORT -c $UPLOAD_SPEED -f $SOURCE --erase --verify

a user has reported on Windows, hey had to force the installation of AVRdude, otherwise they got the following error:

Error: Processing avrcoding101 (platform: atmelmegaavr; board: ATtiny1616)

I assume there should be no reason AVRdude is required in this configuration using a custom upload.

The original issue was described by an enduser.
The problem appears to be related so recent update to platformio. My personal system upgraded this week and now I experience it.
