DOC-5472

Go versions of the Python examples in the time series doc page.

Couple of things to note:

• I've assumed that using 0 and math.MaxInt64 instead of - and + for minimum/maximum timestamps is OK (eg, line 211), but if there's a better way to specify this then let me know.
• Some of the TSMGet/TSMRange examples return maps, so the ordering keys in nondeterministic. I've used code that's a bit more complicated than usual to print out the results in a deterministic way (eg, the example at line 438). If there's a simpler or more idiomatic way to handle this situation then I'll use that instead.
