Added metadata parsing for flash configuration

[ryankurte]

Wow this is an unbelievably smooth experience, great work!

This lets you add metadata to your cargo package to specify the cargo-flash chip argument (and should be simple to extend for any other required options), for example:

[package.metadata]
chip = "STM32F429ZITx"

Questions:

• Are we okay to assume Cargo.toml is in the current directory / is there a better way to do this?
• Non-critical but, is there a reason the commands are all specified using flags rather than subcommands

Thanks for the kind words! We work hard to improve it even more :)

I like the change very much, thanks for doing this! I didn't even know this was possible, tho in theory it should be possible to put any data into the Cargo.toml.

At the moment we can always assume Cargo.toml is in the current dir. cargo-flash works for crates in a workspace, but only if you are in the actual toplevel dir of the crate, not the workspace. This is a bug in cargo-project, which I didn't find time to fix yet. Also, I didn't find time to port everything to cargo-metadata which should not have this issue :)

What flags would you like to see as subcommands? I cannot really see where this would be useful to be honest. If you mean things like reset etc. cargo-flash is really ment just for flashing with a few additions. Flags like --gdb are to be removed in future releases. The new fat client will be cargo-embed (https://probe.rs/guide/tools/cargo-embed, https://github.com/probe-rs/cargo-embed) which can do everything and allows for make-like task configs :)

Could you please run cargo fmt on your changes, such that the CI is happy? :)

Thanks for your contribution!

yeah i picked this trick up from cargo-deb, and it's made extremely easy by cargo_toml.

sweet as

yeah fair, i guess it's really only list-chips that is a separate path
