Jelle Raaijmakers 22d8778437 LibGfx/Matrix: Add inverse() and friends ...

Matrix inversion comes in quite handy in 3D projections, so let's add
`Matrix<N,T>.inverse()`. To support matrix inversion, the following
methods are added:

* `Matrix.first_minor()`
  See: https://en.wikipedia.org/wiki/Minor_(linear_algebra)
* `Matrix.adjugate()`
  See: https://en.wikipedia.org/wiki/Adjugate_matrix
* `Matrix.determinant()`
  See: https://en.wikipedia.org/wiki/Determinant
* `Matrix.inverse()`
  See: https://en.wikipedia.org/wiki/Invertible_matrix
* `Matrix.operator/()`
  To support easy matrix division :-)

Code loosely based on an implementation listed here:
