Negative values for TEXTUAL_FPS freeze the application.

[GEOEGII555]

Setting TEXTUAL_FPS to -1 freezes the application, when it's supposed to ignore the value just like it does if you put 0 or a string into that environment variable.

How to reproduce:

[System.Environment]::SetEnvironmentVariable('TEXTUAL_FPS', '-1')
python3 -m textual

This issue was present in 0.52.1, and it's still present in the latest version (0.84.0). Someone thought about checking for non-numerical strings in the environment variable a long time ago, but no one thought about putting negative numbers in to this day?
