v55.2.0

[apete]

A minor release with a relative short change log, but some things are noteworthy:

• The LP solver is much improved – faster and uses less memory, particularly with larger problems.
• The org.ojalgo.matrix.decomposition package has been refactored internally and an important new interface added – MatrixDecomposition.Updatable. Specifically the LU decompositions are now updatable. If you have an existing LU decomposition and one column of the original matrix changes, you do not need to recalculate the entire decomposition. Instead you can update it with just the modified column as input.
• Apart from the main developer (myself) there are 3 contributors to this release: @hallstromsamuel, @twistedtwin and @Programmer-Magnus. Pretty sure that never happened before, thanks!
