Teensy Loader, in Rust

This is a reimplementation of Teensy loader CLI in Rust.

Usage

cargo install teensy-loader
teensy-loader --help

Pros

• Not written in C
• Accepts ELF binary as input (no need to objconv to an ihex file)
• Supports Teensy 4.0 (not tested yet)

Cons

• Not official, possibly buggy (new project)
• Does not accept ihex input, so it might not fit into existing toolchains
• Works only with libusb (Linux, FreeBSD; tested only on the latter)

I'll accept merge requests that fix the last two cons, as long as they don't break existing functionality. Not going to implement these features, though: what I need is uploading from ELF on FreeBSD.

Future

• A cargo plugin that would make it possible to run cargo teensy-load in a Rust project aimed at a Teensy and it would Just Work (taking Teensy model from Cargo.toml or command-line switch).
