lazy_static
removed, light parser for address URI added (pa…
…ritytech#2250) The `lazy_static` package does not work well in `no-std`: it requires `spin_no_std` feature, which also will propagate into `std` if enabled. This is not what we want. This PR provides simple address uri parser which allows to get rid of _regex_ which was used to parse the address uri, what in turns allows to remove lazy_static. Three regular expressions (`SS58_REGEX`,`SECRET_PHRASE_REGEX`,`JUNCTION_REGEX`) were replaced with the parser which unifies all of them. The new parser does not support Unicode, it is ASCII only.
