Extract the functionality into its own module, as the logic was exactly the same
on both sides.
I've introduced 2 new concepts:
- "own" - the caller of the function, it's either taker or maker,
depending on the OwnParams parameter,
- "other" - the other party, the opposite role.
A threshold is added. This is needed because a malicious user might "change their mind" and publish transactions at any time trying to get out of the contract. The refund timeout should ensure that the refund transaction can only be published if the oracle does not publish a signature.
The buy margin is calculated from `initial_price`, `quantity` and `leverage`.
The sell margin is calculated from `initial_price` and `quantity` (no leverage trading for the seller at the moment).
Includes several refactors:
- Separate API interface for `Cfd` and `CfdOffer` when mapping `toSseEvent`. This allows internal modelling to be different than the exposed API.
- Remove the profit calculation internally, it is only relevant on the UI feed API level.
- Move code that is specific to taker/maker http API from `model` to the respective `routes` module.
- Some simplification of the calculation model of `Usd` (could be further improved by deriving calculation traits)
- Introduces `OfferOrigin` used to save the offer's origin as `mine` and `others` in the database. This is used to properly derive the CFD position from the offer.
By doing a single `cargo build` ahead of time, we are creating all
necessary binaries at once. This allows our cache to work for tests
as well as the binaries.
There is also no need to use release binaries for the smoke test.
Building debug binaries is a lot faster and serves the same purpose:
Checking whether the application actually starts up.
- Add wallet to maker and taker.
For now we have different, static descriptors with a hardcoded DB
path. We also only operate on testnet and use sled as a database.
- Associate each CET with a unique nonce_pk
Eventually a set of `(message, nonce_pk)`.
- Share transactions with maker
- Add serialisation support to adaptor signature

It makes sense to put the `nonce_pk` together with the `message`,
since they're both used to generate the attestation (signature) point.
We also remove the `OracleParams` type since it would only have one
field after this change.
