It seems there just aren't any wheels on PyPI

[chirizxc]

I cloned the repository locally and asked Codex to build the wheel on Windows and I think I've found a few bugs:

import yamlstar

ys = yamlstar.YAMLStar()

data = ys.load("key: 9999999999999999999999999999999999999999999999")
print(data)

Traceback (most recent call last):
  File "C:\Users\chiri\Desktop\Rust\yaml-rs\test.py", line 5, in <module>
    data = ys.load("key: 9999999999999999999999999999999999999999999999")
  File "C:\Users\chiri\Desktop\Rust\yaml-rs\.venv\Lib\site-packages\yamlstar\__init__.py", line 159, in load
    raise Exception(self.error['cause'])

import yamlstar

ys = yamlstar.YAMLStar()

data = ys.load("x: ! 99")  # must be {'x': '99'} ('99' is <class 'str'>)
print(data)

Traceback (most recent call last):
  File "C:\Users\chiri\Desktop\Rust\yaml-rs\test.py", line 5, in <module>

import yamlstar

ys = yamlstar.YAMLStar()

yaml = """\
# sets are represented as a
# mapping where each key is
# associated with the empty string
--- !!set
? Mark McGwire
? Sammy Sosa
? Ken Griff
"""
data = ys.load(yaml)
print(data)

{'Mark McGwire': '', 'Sammy Sosa': '', 'Ken Griff': ''}

but must be python set: {'Mark McGwire', 'Ken Griff', 'Sammy Sosa'}

[chirizxc]

I also have some ready-to-use code for testing the yaml-test-suite for Python:

@chirizxc Thanks for this. I'll take a look soon!
