repair or remove expfit-galaxi

Fit example expfit-galaxi currently generates very bad fits. This needs to be repaired; otherwise it would be better to remove the example.

On the road from v19 to v20, the distribution of particle radii was outcommented. This needs to be repaired first.

• Improve errmsg from importing sample
• By default, import function get_sample()
• Restore means to rotate detector

added Example Fit bug labels

changed the description

Before the recent workshop I temporarily restored distributions in expfit-galaxi and found that for the same sampling size it works much slower than in v1.19.

Also bad, but not my first concern.
