Major changes

• Revised treatment of X chromosome in "general AIL" cross type, to be the same as the autosomes but with 2/3 as many generations for recombination. This should provide a better approximation.

Minor changes

• Revised reduce_markers() so that it can handle the case of many markers, by working with them in smaller batches.

• fit1() now returns both fitted values and residuals.

• fit1() can be run with genotype probabilities omitted, in which case an intercept column of 1's is used (Issue #151).

• Updated mouse gene database with 2020-09-07 data from MGI.

• Implemented Issue #184, to make calc_het() multi-core.

• Made the vdiffr package optional: only test the plots locally, and only if vdiffr is installed.

• calc_sdp() can now take a plain vector (Issue #142).

• Added a lodcolumn argument to maxlod() (Issue #137).
