Add mMUCH v20a, by Om Chaudhry, which fixes the orientation of the cooling plate and shifts mMUCH to the correct position, refs #1725

Add three STS geometries v19k,l,m which have asymmetric ladder configuration and differ in the spacing between sensors in z-direction, refs #1730

A consultation with our electronics expert resulted in
a larger expected material budget for our front-end electronics
which is why the heatsinks hosting them were further increased
in thickness.
Now the electronics are represented by 7mm aluminium
equivalent (x/X0=7.9%) instead of 3mm (x/X0=3.4%)
as in the parent commit.

The new tof geometries v16d solve the problem with redefined media.

The new geometries contain then same geometry layout as in v16c but
stored in the new exported geometry file format.

Variants:

* v20a: stations at old location but all changes reported below in
* v20b: as v20a, but TPG carrier thickness increased to
  500 µm, all stations moved upstream by 4cm.
* v20c: as v20a but moved upstream by 4cm.

Detailed changes in those new geometries are:

* Position of the MVD moved 4cm upstream (v20b & v20c),
* TPG carriers' thickness updated (from 300 µm in v17 to 380 µm [500 µm]),
* MVD specifc custom materials defined in media.geo (TPG, diamond, glue, fpc),
* CVD diamond only used for first station on VX version,
* transformation matrix added to the ROOT output file
  placing the detector in the CBM coordinate system,
* addition of a top and bottom mounting plate of 10mm aluminium,
* vertical aluminium heatsinks' thickness increased by 3mm to mock
  the expected material from FEBs that will be mounted on top of them.

add geometries related to the long STS v19i, a streched PIPE v16d_1e, the 40 mm translated MVD v17b VX and TR geometries and a corresponding setup file, refs #1649 #1690

Only setups are updated which are in the test suite. Refs #1311

All include geometries weren't changed. Instead of writing the volumes
to the file the volumes are now exported and the placement matrix added
to the file. The new file format solves a problem that for some volumes
the media was changed when combining the different detector geometries
to the complete experimental setup. Refs #1535

Add new psd geometries for the sis100 electron setup
Change the setups for sis100_electron and sis300_electron
to use the correct psd geometries. Refs #1584.
