+pow performance degrades rapidly as the exponent grows. Here we replace the +sqt implementation that calls +pow with one that uses the Newton-Raphson method. This gives way better performance, and more accurate results to boot.

Implements +asin, +acos and +atan. The former two are implemented in terms of the latter, which is implemented as a Taylor expansion. We also include the two-argument variant of +atan, +atan2, for completeness.
To keep the numericists at ease.

ames: add %tune to $sign to not break old queued-events
The runtime makes the http requests for double boot protection using the standard C `%d` format but the endpoint in eyre expects the bone to be `@ud` formatted. This causes a mismatch if the ping-bone is larger than 1000, causing double boot protection to become disabled. We address the mismatch in arvo instead of vere because this is easier to release.
math: better +sqt with newton's method
math: inverse trigonometric functions
