Fix maxint() typo, spotted and reported by Laszlo.
Prevent program from hitting Stata's limitations when nquantiles is large (>245).
Make readme title smaller
Fix discrepancy where fastxtile ignored duplicate cutpoints while xtile respects them, generating different results. The behaviour now matches xtile for non-unique quantiles stored in cutpoints().
Speed up fastxtile handling of cutpoints -- Stata is much faster at accessing scalars than matrices.
Fix crash when cutvalues() has many values, due to Stata string length limitation.
Merge branch 'release/v1.22'
