Remove uninspect dependency

[hellow554]

On my arch linux I have python 3.13, which clearly is supported, since the readme states 3.7+ ;)

The problem when trying to install magma-lang via pip:

ERROR: Ignored the following versions that require a different python version: 0.7 Requires-Python >=3.6, <3.7; 0.8 Requires-Python >=3.6, <3.7
ERROR: Could not find a version that satisfies the requirement uinspect (from magma-lang) (from versions: none)

There aren't many places where uninspect is used, so I think it would be quiet easy to remove that dependency and convert it to the official inspect lib.

Thanks a lot!

Btw, circt isn't supported as well:

ERROR: Ignored the following versions that require a different python version: 0.7 Requires-Python >=3.6, <3.7; 0.8 Requires-Python >=3.6, <3.7
ERROR: Could not find a version that satisfies the requirement circt==1.66.0 (from magma-lang) (from versions: 1.100.0, 1.100.1.dev8, 1.100.1.dev25, 1.101.0, 1.101.1.dev2, 1.102.0, 1.102.1.dev8, 1.103.0, 1.103.1.dev7, 1.104.0, 1.104.1.dev4, 1.105.0, 1.105.1.dev7, 1.105.1.dev19, 1.106.0, 1.107.0, 1.107.1.dev1, 1.108.0, 1.108.1.dev3)

is there a reason for that version pinning?
