Return High Precision Time Since Boot

secfrac = profiler.time()

Returns a high precision, microsecond resolution, time.
secfrac is seconds, with the fractional part representing microseconds.

Hint

Use this to time and profile Lua functions for debug.

e.g.

time1 = profiler.time() -- --> time1 = 25.593903
...
time2 = profiler.time() -- --> time2 = 73.294220
