Create the a handler to request a new result

route: PUT `/results/:chain_id/:round_id/:algorithm`

* validates parameters:
* requires chain_id to be a number
* requires round_id to be a valid hex string or compatible with all the ids we have
* requires algorithm (validate if it's included in `["cluster-matching", ...]` add others later)
* creates a new record in the `results` table setting:
* `created_at` to `now`
* `generated_at` to `null`
* `started_at` to `null`
* `finished_at` to `null`
* `last_requested_at` to `now`
* `file_url` to `null`

notes:

in the next tickets we will:
* validate if the round chainId/roundId exists
* check if a calculation already exists and redirect to its GET route
