3.8

Enhancement:

A new type was introduced in 3.7 (announcement has been forgotten): a vhighlight to be able to hightlight a whole region across all tracks.
Much more parameters for vhighlight and vlines
- 'zorder' to set it on top or behind.
- 'line_width', 'color', 'alpha', 'border_color' for vhighlight and 'line_style' for vlines
You can now set multiple vlines
For gtf, the output of make_tracks_file set prefered_name to gene_name instead of transcript_name.

Support mcool files for hic_matrix_square. This solves #404
Works with gffutils version 0.11.0 where ValueError became gffutils.exceptions.EmptyInputError for empty gtf.
The installation instructions have been updated
Fixed a small bug in links track with "use_middle" enabled, where midpoints could have different ordering than start points (Thanks to @Jeff1995 ).
Fix a bug when plotting gtf in the middle of a large intron.
Fix plot genes with orientation = inverted
Support Numpy 1.24, drop support below 1.20
