Cookie name with 'special symbols'

[nordicdyno]

Cookie names not escaped in search pattern. Now this is user's side work.
It would be much better and more natural to esape names like it done in this code (function escape_lua_pattern):
https://github.com/lua-nucleo/lua-nucleo/blob/master/lua-nucleo/string.lua#L247

Otherwise it's easy make mistakes in code like that:

val = r.cookies["some-session-id"]

P.S.
Also there is no method in API to fetch all cookies. I think it would be useful.
