Update SPMT to Python 3.10 - PEP498 Literal String Interpolation

[Liquid369]

This pull request is updating the entire codebase to PEP 498 standards using fstrings.

This PEP proposed a new syntax for formatting strings that is more concise, readable, and less error-prone compared to other string formatting methods like str.format() or % formatting. F-strings allow you to embed expressions inside string literals by prefixing the string with f or F and enclosing the expressions within curly braces {}.

I have updated every file to this standard and tested that our application is still functioning.

We have in this the added PyQt version bumped to 5.15.10
Then we have also set wheel and setup tools to specific versions to avoid any of our dependancies with setup.py warnings on depreciation coming.

There is a small update in the spmt.py that is not the fstrings, but for testing purposes I needed to convert the splash sizing into an integer to load. This can be removed for a different fix, or whichever.

some changes needed, see inline comments.

Also, the timeThis function in src/misc.py needs updating as newer versions of python no longer have the time.clock() function:

Fixed all review suggestions.

Thanks for those catches!

i've tested as much as I can using this PR with the changes suggested. without a dedicated test framework this is the best we can do.
