🐛 Fix compulsory inPort args in new compiler

[MFA-X-AI]

Description

Currently the new compiler does not compile any xircuits canvas that has compulsory inPorts which is indicated as [★]. As currently Xircuits bakes the ★ into the label, it breaks the compiler due to ★ being a a special character.
This PR updates the compiler to read .xircuits files using utf-8 encoding, then filters ★ from port strings.

Thanks for the PR,

I have faced this issue with building xircuits or using the branch wheel:

• Any Xircuits examples with CompArg is compiling to an empty python script.
• Xircuits examples without CompArg are fine.

Ah thanks for catching that. I only tested the compile using the xircuits-compile command, turns out the compile from in-Xircuits does call it from a different place. Should be fixed now.
