Add support for differing binary names

[hisbaan]

For example, my package, didyoumean builds a binary called dym with this addition to the Cargo.toml file:

[[bin]]
name = "dym"
path = "src/main.rs"

The script fails when running strip as the binary name is not as the script expects. The issue is with line 246 of main.rs: binary.push(&package.name); which assumes that package.name is the same as the produced binary.

I don't know enough about Cargo.toml parsing so I'm not sure how to parse a new field exactly and to change the binary path optionally if that field exists, however I would be glad to work on it if someone could point me in the right direction.

This would be an easy fix for me, let me take care of it. Thanks for bringing this to my attention.

Awesome! Thank you so much :) It's a relatively niche configuration I suppose

I've put up a PR that implements this.
