feat: convert into a library

[moliholy]

This PR essentially transforms the current repository into a mixture of binary/library. The main idea is that other projects can import psvm as a library and utilize its public API.

Tests are failing, but also in the main branch. It should be automatically fixed once they are fixed in the main branch.

EDIT: On a second thought, perhaps it's just in my local machine. Let's see what the CI says.

Looks good, thanks. Is it a library crate now? I dont see a [lib] entry, i think that is needed.

[moliholy]

@ggwpez it is, yes. Simply create a new project with cargo init and add this line to the dependencies:

[dependencies]
psvm = { git = "https://github.com/moliholy/psvm", branch = "feat/convert-to-library" }

Then in the main.rs or lib.rs file you'll be able to import psvm.

I dont see a [lib] entry, i think that is needed.

AFAIK you don’t need a [lib] section to make a crate importable as a library. If the project has a src/lib.rs, Cargo automatically creates a library target.

Looks good to me! Thanks for the contribution. Will fix compilation warning and failing test in another PR, it is also failing in main branch, might be cause target branch (of the test) on Polkadot SDK changed. Will publish to crates.io after this.
