Compile regex once and reuse it instead of recompiling it for each line
parsed. Resulted in a speedup of 1.2 for an example OEM loading test
case.

Fixes issue #640

An archive for sources can be downloaded
directly from Gitlab, in pages related to
tags or releases.

Fixes #639

The effective real download is on Maven Central.
The projects's Nexus is used for releasing
process.

Remove a point discontinuity and canceled terms analytically to avoid
catestrophic cancellation. Added a test case, thanks to qmor for
reporting the issue.

Fixes #639

This should now avoid numerical issues when computing the discriminant.

Fixes issue #639.

Previously TSF.getGMST(conventions, simpleEop) would always return the
same value regardless of the parameters. Pull up the implementations of
getGMST and getUT1 from PreloadedTimeScales to AbstractTimeScales and
used them in LazyLoadedTimeScales. Added test cases for
LazyLoadedTimeScales.

Fixes #627

The toString() methods of CartesianOrbit, FieldCartesianOrbit,
TimeStampedFieldPVCoordinates, and TimeStampedPVCoordinates used the
default data context by appending a date to a string. Modified
CartesianOrbit to only use the six defining elements like is done for
the other subclasses of Orbit. Added a toString(TimeScale) method to
TimeStampedPVCoordinates and modified the field version to call it.

Peviously UT1 and therefore Earth rotation angle was off by 1s during a
leap second. Fixed by having EOPHistory cosider the discontinuity to
occur at the start of the leap second as does UTCScale.

There are just too many use of the default data context in the tests,
and they are intentional: tests finds their data by just configuring the
default data context, not by implementing a dedicated context.
