Syntax error fix

[Lsatric]

In finsta360.py its a line called:

print('finsta360.py : to finalize incomplete MP4 of Insta360 ONE-X

To make the script work I had to add ') after X to make it consistent like this:

print('finsta360.py : to finalize incomplete MP4 of Insta360 ONE-X')
print('https://github.com/kichiki/finsta360')
print('USAGE: finsta360.py [options]')

Thanks, I had the same issue running the script on my Mac and adding ') to the end of line 959 fixed it.
