TEOB geom and cleanup

Description

This small MR fixes geometric units on the time axis (previously only prefactors were correctly handled), and removes a small unused function.

Geomtric edits do not have any impact on LVK analyses, and are only used to facilitate comparison with NR.

Tests

I have tested that when activating geometric units, comparisons with NR through bayRing works.

I have tested that these edits do not impact standard LVK analyses, by running a quick analysis.
