Add bin section

[SergioGasquez]

With this change the generated bin will have the project name instead of main, this helps with using esp-template in Wokwi

I don't know much about Wokwi but

elf = "target/{{ rust_target }}/debug/{{ project-name }}"
firmware = "target/{{ rust_target }}/debug/{{ project-name }}"

shouldn't it use release there?

I also thought about a improving the INCLUDEFILE functionality to support renaming the target file - might also work if we always name it main.rs?

I think its useful to use debug as Wokwi is used, many times, to debug. But no hard opinion here.

TBH, I didnt noticed that wowki.toml was not working, this PR should also fix it. By making Wokwi things simpler, I meant the wokwi-builders we use for Wokwi web version
