Increased requested velocity since we're not blending between feed and rapid
Added missing type checks for LineArc and ArcLine
Cleaned up test files
Refactored common initializations out in blendmath
Whitespace fixes
Added improved max velocity calculation for blend arc

Estimate the blend arc's maximum velocity by the triangle altitude
method, allowing higher cornering speeds for axes with dissimilar
accelerations.
Merge branch 'feature/velocity-limits' into circular-blend-arc-experimental3
Removed old comments
TP: removed extraneous rtapi_print
TP: Possible fix for circular segment slowdown w/ parabolic blends
canon: Slight refactor of ARC_FEED to isolate velocity / accel calculation
Revert "Fix arc acceleration constraint"

The acceleration violation was a parabolic blending issue that has been
fixed by limiting tangential acceleration and max velocity in arc segments.

This reverts commit bfb837ef97113a311b9e431855a7390ddcc34c80.

Added missing test files
Added symlinks back and misc octave scripts
Additional test files for arc cases
