This commit improves the performance of the reference check for large
categories of Units of Measure (UoM).
After this commit, the number of UoMs in the category is counted using
the read_group method instead, resulting in faster performance.
Benchmark:
| Nbr of UoM | Before | After |
| ---------: | -----: | ----: |
| 0 | 0ms | 0ms |
| 1 | 1ms | 1ms |
| 30 | 6ms | 3ms |
| 200 | 7ms | 2ms |
| 18000 | 900ms | 15ms |
