ValueError: invalid literal for int() with base 10: '1.7e+07'

[sigven]

in pcgr_summarise, there is a bug for one (or more) selected transcripts in the calculation of distance to coding sequence start, given the scientific encoding of the coding sequence start (1.7e+07) that is not properly handled during conversion to integer.

Version of PCGR: 2.1.0
Genome build: grch37
