Performance: 15%+ loop/sec speedup by optimising 3d table bilinear interpolation (#735) * Bi-linear interpolation - round towards nearest integer Add the equivalent of 0.5 to the final calculation pre-rounding. This will have the effect of rounding to the nearest integer, rather than truncating. I.e. rounding down * Unit tests: isolate table tests and check interpolation x/y bins * Unit tests: add native table3d tests * Unit tests: derive min/max from axis test values * Unit tests: more detailed messages * Unit tests: fix rounding & unit tests * Performance * Performance: use uint16_t instead of unsigned long for the fixed point math: we only need the fractional part. I.e. 1.16 not 16.16 * Use narrowest possible type * Optimise bin position logic for performance * Only promote to uint32_t when really required. * Simplify bin checks - no zero width bins * Save memory: use a single byte for the last bin caches * Performance: increment pointers instead of repeatedly dereferncing array by index. * Comments * Incorrect array underrun logic * Rename type, comments * Fix unit tests
