Implement From trait between Address and String about algonaut

[ivanschuetz]

Hi! I'm considering working on this. There are several possibilities and wanted to clarify first:
(not super experienced with Rust, apologize for possible oversights)

• TryFrom trait (since it can fail): this seems to require a bit awkward syntax when passing String, e.g:

Address::from_str(&*gen_response.address)
// or
(&*gen_response.address).try_into()

• FromStr trait:

Address::from_str(&gen_response.address)
// or
gen_response.address.parse::<Address>()?

To convert to string, we'd to implement the ToString trait.

Hi @i-schuetz ! I was thinking of this issue just yesterday, thanks for the analysis! In fact my doubt was the requirement for perfect conversion of the From trait and your solutions perfectly address the issue. I would go with the first option because I think that we will be using it especially with string slices and because the try_into feels cleaner than parse::<Address>. In theory we could implement both, but I think that is better to keep a single way of doing things whenever possible. What do you think?

With parse actually we don't have to set the type, unless type inference doesn't work (which happens only in 2 places at the moment). Given this, I'm slightly in favor of it, as "parse" sounds a bit more accurate (and we don't need the &* syntax, which we'd need with TryInto, also in 2 places). I'll open the PR with this. Can change it.
