* register-command-first-pass:
  Add sourcehut CI
  Add Rakefile to run all tests
  Initial registration flow for Bitcoin
  Registrations that start on the web will have a tel selected already
  Helpers for doing Electrum RPC
  Add helper to fetch current BTC sell prices
  Allow skipping tests without being caught in pry

This is the Bitcoin "happy path" where there is already a tel and a customer_id.
Gets all the way to generating a BTC address for payment and quoting an amount.
Stubs out flows for credit card and activation code as well, but does not
implement those flows.

TBD: after bitcoin payment comes in and jmp-pay activates the account, we should
come back here to actually buy the number, select a new one if no longer
available, etc.

So, manage any already-known tel selections and allow registration to use them
right away.  In the future this will fall back to letting the user search for a
tel over XMPP, but that is not implemented here.

Scrapes the sell price for Bitcoin from canadianbitcoins.com
USD price is done by converting this CAD sell price to USD via openexchangerates

Rubocop clean. Good test coverage of helper objects.

Look up the user's plan to find out what currency to charge them in.

We'd like to actually get the money, not just be allowed to.

Supports registering with backend SGX via basic iq:register.

Does not support data forms version with nice labels.

Does not verify billing or anything else yet, just unconditionally registers the user.
