v2.1.0

[2.1.0] - 2022-03-31

Changed

• All instances of linalg.inv now use linalg.pinv. All APIs are still the same, but this is potentially a backwards breaking change as previous results may be different from new results. This will mainly affect standard error calculations.
• Previously calc_slopes was called after every least squares fit in optimization routines trying to find breakpoints. This would occasionally raise a numpy RuntimeWarning if two breakpoints were the same, or if a breakpoint was on the boundary. Now calc_slopes is not called during experimental breakpoint calculation, which should no longer raise this warning for most users. Slopes will still be calculated once optimal breakpoints are found!
