Investigate Integrating fmt

[KStocky]

Is your feature request related to a problem? Please describe.
There are places where I want to format a runtime quantity of arguments into a string. std::format does not support this. I can create a format string at runtime, but the arguments must be known at compile time. fmt does support this. Here are the docs for it. dynamic argument lists Using that would allow me to get rid of stringstreams which would be nice.

Describe the solution you'd like

1. Integrate fmt
2. See if it can replace stringstreams

Describe alternatives you've considered
Currently I am using string streams. They work but I do much prefer fmt style formatting
