Normalize Phone Numbers

[kdeldycke]

Just happened to have an issue on setting up a new Revolut account on Bisq: the phone number I registered is taken as-is and will be displayed as such to the receiving end of the transaction.

I entered my Revolut account's phone number in the local (French) format, i.e. 0612345678 and the other party, not located in the same country as I am, did not find my account. It had to be formatted in the international form: + 33 6 12 34 56 78.

I failed my first transaction on Revolut for that reason. But was able to solve the dispute thanks to a great arbitrator.

To fix this issue for good and reduce the number of disputes, I propose to have all phone number fields in Bisq normalised into their international form.

Good news, there's a great library made by Google to normalise all of them at: https://github.com/google/libphonenumber . Used it myself, it's solid, well maintained and clean! :)

I'm working on a validator / formatter and tests for this issue. Please let me know what objections there are to this approach:

• Adding a new 343 kB Google libphonenumber dependency.

• Converting all input phone numbers to E.164 format. @kdeldycke's example input 0612345678 would be re-formatted as +33612345678.
