phidget 0.4.1

# GitHub Actions CI check for the 'phidgets-rs' Rust crate
#
# It does the following:
# - Format check of the sources using nightly
# - Build check using the current stable compiler and the MSRV version.
# - Clippy check using the MSRV compiler
#
# Note that the current MSRV predates the new cargo resolver, v3, so we go
# out of or way to use it from stable to create a Cargo.lock file that 
# properly resolves dependencies for the MSRV.
