Update requrements.txt to ensure correct version of numpy is used for Python 3.7
Tested by wiping and reinstalling RMS from scratch on my spare Pi4, then rolling back numpy to 1.18.3 and running RMS_FirstRun.sh.
As expected, this installed numpy 1.21.6 which is compatible with Python 3.7 and is also compatible with pyqtgraph==0.12.0, which was also installed. Afterward, RMS started cleanly.
