The trickery is that we compare the path's elements with the group names which we want to rename
and substitute those path's elements accordingly.
And if for a certain element we need to create several groups, then paths get duplicated with those names:
Example:
we have `entry/instrument/detector_group` in the schema, and
`detector_group` are [`DET_1`, `DET_2`]. Then we've got two paths as the result:
[`entry/instrument/DET_1`, `entry/instrument/DET_2`]
