Improve regular expressions report data

[hugo-vrijswijk]

In recent releases, there have been 2 major improvements in weapon-regex for regular expressions mutations:

1. The description field has improved description including the location and more detail for the mutation:

// Before (same for all mutants)
"Negate character class"
// After
"[0:0, 0:1) Negate the character class `[ab0-9[A-Z][cd]]` to `[^ab0-9[A-Z][cd]]`"
"[0:6, 0:7) Negate the character class `[A-Z]` to `[^A-Z]`"
"[0:11, 0:12) Negate the character class `[cd]` to `[^cd]`"

Example:

2. A new field was added to Mutant called replacement which can be used in combination with location to get very precise replacements in the report, instead of the whole string as the location.

Example:
