metadata string added for inscribe file

[MBenz12]

1. In casey ord github repo (https://github.com/casey/ord). There is a inscribe command situated at this path (https://github.com/casey/ord/blob/master/src/subcommand/wallet/inscribe.rs). We need add to start accepting a new parameter in this file.
   Purpose of this param - this param will let anyone pass an additional string param and will attach this param to the meta information of the file.

Example,
ord wallet inscribe FILE --metadata "metada_string"

2. After the above, your inscription struct (https://github.com/casey/ord/blob/master/src/inscription.rs) will have the meta information that we attached to this. This struct powers this template (https://github.com/casey/ord/blob/master/src/templates/inscription.rs). So what we need to do is, start displaying meta information in this view.
   Currently this view looks like this (https://ordinals.com/inscription/431fea141cfc2e6f8dda9c209fbe9ce411e9e158d48661e86cbd0cc5e0bc33f5i0)
   It should show meta information somwhere that we attached

With the code you've provided, nothing would actually be done with the metadata. It wouldn't be written in the inscription transaction and it wouldn't be read when an inscription is parsed from the blockchain. It'd need a tag and correct builder/parser logic for that. Take a look at https://github.com/casey/ord/pull/1713 for an example of how that can be implemented.

thanks for your advice @tyjvazum
I've added that features,
could you please review my code again?

[tyjvazum]

That looks reasonable to me, but the tag should be an odd number since even numbers break backward compatibility, causing the inscription to be ignored. There should also be some tests for it. Hopefully a collaborator will merge it, because metadata is a great feature that ideally should have been in place from day one.

Hey mate @MBenz12 ,
Glad to see you raised a PR with same technical solution which I suggested you in discord. Would have been better if you could have told me that you also want to contribute here.
Reference - Issue
We have already raised PR to Casey's open issue for traits. Would request to help us in getting that PR merged or you can further contribute in the PR to improve it further. Let's work together to make Ordinals more strong ecosystem :)
