v1.45.4

RELEASE NOTES FOR SeqMonk v1.45.4

This release is a bugfix release for the last version which resolves
an issue where small probes might not be drawn in the chromsome view
if their inferred size was less than 1 pixel.

It also introduces a copule of other minor changes:

1. Fix a probe drawing optimisation bug which caused some small probes
   not to be drawn.

2. Add the option to highlight replicate sets in the line graph.

3. Annotate the variance filter results with the actual variance
   values which were used for the test.

4. Improved the efficiency of drawing raw reads in the chromosome view
   for replicate sets and data groups.
