add serde support

[vauradkar]

Sending metadata across systems would be very convenient if the tags support serde. Would you be willing to take a patch like this main...vauradkar:rust-id3:main ?

I have considered this in the past, but concluded that it would make little sense for a crate that already implements a serialization format.

What is your use case?

[vauradkar]

Client-server based tag processing. Client doesn't play or process audio. So server doesn't need to load or send entire audio file. serde makes it convenient also in the sense that wire format(bincode, json, toml, etc) is independent of the id3 library.
