Fix float addressable gcode without integer part expressed in gcode file

[mauroalderete]

Description

Often, PrusaSlicer generates a gcode file using float32 gcodes without integer part expressed. G1 Z.35 F7800 I change regexp to support this format. Additional, simplify the regexp to ignore comments and checksum sections since these structs are discarded in previous steps.

How Has This Been Tested?

Add two cases in TestParse
