Full Changelog: https://github.com/tusharsadhwani/zxpy/compare/1.5.1...1.5.2

• use read1() instead of select polling, to simplify some logic
• remove the use of echo -n, as that is linux-specific

Adds Python3.10 support

• Use the select module to do non-blocking reads from the shell process, instead of reading 1 byte at a time. Leads to significantly faster output for large streams, without any blocking.
• Use process.communicate() to read stdout and stderr without causing deadlock due to buffer overflow.

• Ensure the package actually works in Python 3.6+
• Make sure that ~'...' raises an error if the process exits with a non-zero return code
• Fix an edge case in supported syntax: [a, b, c] = ~'...'

Now you can pass whole commands as variables inside f-strings, without quoting.

Take this piece of code:

>>> cmd = 'uname -a'
>>> ~f'{cmd}'
/bin/sh: 1: uname -a: not found 

This is because uname -a was quoted into 'uname -a' to avoid shell injection.

To avoid this, support for :raw format_spec as added:

>>> cmd = 'uname -a'
>>> ~f'{cmd:raw}'
Linux pop-os 5.11.0 [...] x86_64 GNU/Linux

Note that this shouldn't be used with external data, or this will expose you to shell injection.
