FEAT: Add additional validation to validator.py that provides command count

[cantechit]

Feature Req: The existing validator.py doesn't provide enough granular information about why light-show output files from xLights are too large, the Memory % value seems to wildly fluctuate higher even when commands are removed

[bendudz]

The validation results give a frame count if the FSEQ is valid. The documentation states max command count (transition of light / closure state ie on -> off / open -> closed etc) is 681 but bear in mind, commands that start at the same timestamp counts as 1 command.

Memory usage is calculated taking the number of commands & dividing it by 681.

I’ve revisited your comments & now include total commands used in my PR #20

+1, was looking for this

Good suggestion. We'll make this change.
