ch57x-keyboard-tool: add version 1.7.0

Utility to program CH57x USB macro keypads (1189:8840/8842/8850/8890)
by uploading a YAML key/knob mapping to the device. Rust crates are
listed in DOWNLOAD and vendored for an offline cargo build. Ships a
uaccess udev rule so the logged-in user can program the keypad.
