fix: increased float rounding precision for CRF parser (#1369)

Browse source 
* increased float rounding precision for crf parser

* limited fractions to a max denominator of 32 to prevent weirdly specific values

* add test cases for 1/8 and 1/32

* add rounding to avoid more digits than necessary
