Questions regarding the template project

[yanshay]

I leant about this tool just now after using cargo generate esp-rs/esp-template projects till today, and noticed this tool generates the project somewhat differently. I wanted to understand why.

The two differences I saw and interested to understand:

1. Why is it created as a lib with asyn_main.rs under a bin folder rather than just src\main.rs?
2. Why is build.rs used for setting the rustc-link-arg-bins=-Tlinkall.x instead of config.toml?

We recently replaced the cargo-generate template with this approach since it's more flexible and user-friendly - we already can imagine adding a few interesting things in future

1. Main reason for this is to make it easier for us to maintain the template. For users it could make things easier if they want to split their code into a library and the actual binary or have multiple binaries but honestly that wasn't the real reason
2. We already did that with esp-template: https://github.com/esp-rs/esp-template/blob/d0217ac27edd1cde58189a02cfe110fb9b621bd8/build.rs#L2 - I really have no opinion on that since both, the config.toml and the build.rs approach do the same thing
