Bugfix preprocessing of ring geometry

Version checks

• I have checked that this issue has not already been reported.
• I have checked that this bug exists on the latest version.

Reproducible Example

Has its origin in the Santa Cruz project and therefore santacruz branch. Depending on the type of projection, the code to remove duplicate in ring geometries may incorrectly assume that some points are duplicates. For some projections the relative 'magnitude' of 0.5 meter can be vary small compared to the x or y value. Therefore the tolerances of the code should be adressed in

hydromt_delft3dfm/hydromt_delft3dfm/workflows/branches.py

Line 1231 in 73b79bf

duplicate_ids = np.isclose(first_nodes, last_nodes)

Current behaviour

Some points in ring geometries are incorrectly assumed to be duplicates

Desired behaviour

Adjust tolerances to relax this check
