fixed Python 2 compatibility
...
Python 2 returns the string representation with just calling
writeframes(data) instead of writeframes(data.tostring())

This change adds an escape hatch that could work for both major Python
versions, except Python 3.0 and 3.1 but those should be rare and
unsupported anyway.

Removed tostring() in write_wav. Python 3.9+ has removed the tostring() methods from array.array and other primitives.

gen_values: fixed FM sample repetition bug
...
In the previous version, the FM modulator issued the last sample of the
previous frequency-time tuple twice, once as the last sample of the
previous tuple, once as the first sample (sample = 0) of the next one.

gen_values: initialize local variable 'sample'
...
although in practice, this shouldn't happen -- I tried lowering the
sample rate, and even at 10 samples/sec with Martin M1, it worked, and
SSTV requires at least 4000 samples/sec
(1 sample/sec raises an error though, if you'd like to try)
