Suggestion: Python bindings

Hey, @WerWolv Nik!

Your Pattern Language is great. I like to use within ImHex software. But now I have a use case that doesn't covered at all.

A desktop application that read binary files and integrates with already existing source code based on Python language. I would like to see pypl (python pattern language) instead of PatternLanguage CLI.

The use case is that:

from pypl import PatternLanguage

with open("tests/data/test_data", "rb") as f:
    data = f.read()
with open("tests/data/test.hexpat", "rb") as f:
    patt = f.read()

pl = PatternLanguage()
output = pl.format(data, patt)
print(output) # that output is dict

What you think about that? Can it be official release in the same repo or separate repository of python bindings (at least format subcommand)

Review the existing PatternLanguage CLI and its mentioned format subcommand, using tests/data/test_data and tests/data/test.hexpat as the example inputs. Determine the binding boundary and whether the proposed format API can return a dictionary; done means a documented decision and scoped plan for official or separate Python bindings.
