Output from `tidy-IncrementsRelativeParts` is sub-optimal

The intervals and increments tibbles should probably combined, in a manner similar to

.DefaultIncrementsRelative() %>% tidy()
# A tibble: 2 × 3
    min   max increment
  <dbl> <dbl>     <dbl>
1     0    20      1   
2    20   Inf      0.33

If done, knit_print.IncrementsRelativeParts will need to be modified. This will be straightforward.

.. and similarly for IncrementsRelativeDLTCurrent /knit_print.IncrementsRelativeDLTCurrent and IncrementsRelativeDLT /knit_print.IncrementsRelativeDLT.
