Title: Bugs and enhancements in weightstats

full test coverage now 98% verified, but not all options

fixed a few bugs, added some options
added TOST

still missing:

edit docstrings
check interface, function/method arguments
nice printing of test results,
maybe: return distribution instance
compare ttest with ANOVA and OLS/WLS

not checked: compare and tests when data is 2d, might require 1d in CompareMeans

should we merge paired and independent ttests, same for tost
