LiquidInterpolatable::Filters#unescape_replacement

Unescape a replacement text for use in the second argument of
gsub/sub.  The following escape sequences are recognized:

- "\\" (backslash itself)
- "\a" (alert)
- "\b" (backspace)
- "\e" (escape)
- "\f" (form feed)
- "\n" (new line)
- "\r" (carriage return)
- "\s" (space)
- "\t" (horizontal tab)
- "\u{XXXX}" (unicode codepoint)
- "\v" (vertical tab)
- "\xXX" (hexadecimal character)
- "\1".."\9" (numbered capture groups)
- "\+" (last capture group)
- "\k<name>" (named capture group)
- "\&" or "\0" (complete matched text)
- "\`" (string before match)
- "\'" (string after match)

Octal escape sequences are deliberately unsupported to avoid
conflict with numbered capture groups.  Rather obscure Emacs
style character codes ("\C-x", "\M-\C-x" etc.) are also omitted
from this implementation.
