Brendan RobertandClaude 3d359f0a0e Add hardware acceleration for scalb, compXY, and annuityXY functions 
Implemented hardware-accelerated versions of three additional functions:

- scalb(x, n): Binary scale operation (x * 2^n) using pow2X and mul
- compXY(rate, periods): Compound interest ((1+rate)^periods) using powXY
- annuityXY(rate, periods): Annuity calculation using powXY

This brings the total hardware-accelerated functions from 28 to 31 out of
40 total SANE operations (78% coverage). These functions leverage the
existing hardware-accelerated powXY implementation, combined with
mathematical identities to avoid SANE fallback.

All functions maintain full API compatibility and automatically fall back
to SANE if MegaFlash hardware is not available.

Updated documentation to reflect new accelerated function count and
reorganized function categories.

Brendan Robert 6839f068ab Extend hardware acceleration to all log/exp functions using properties 
Implemented all remaining logarithm and exponential functions using
properties of logarithms and hardware acceleration:

New Hardware-Accelerated Functions:
- ln1X (ln(1+x)) = ln(1 + x) using hardware ln
- log21X (log2(1+x)) = ln(1+x) / ln(2)
- pow21X (2^x - 1) = e^(x*ln(2)) - 1
- powE1X (e^x - 1) = exp(x) - 1
- powE21X (e^(2x) - 1) = exp(2x) - 1
- powXInt (x^n) = e^(n * ln(x))
- powXY (x^y) = e^(y * ln(x))

Now have **28 total hardware-accelerated functions**:
- 9 direct from MegaFlash FPU
- 19 via mathematical identities

Only 9 functions still use SANE fallback:
- add, sub, rem, type, cmp, trunc, round, logb, scalb
- compXY, annuityXY, randNum (financial/random)

This dramatically expands hardware acceleration coverage while
maintaining full API compatibility and precision.
