Update script to find missing routes

[Roznovjak]

With #1250 we will be able to generate TC proposals to add routes to the pallet-route-executor. Update the script so we will be also able to detect missing routes. We mainly need to set up the routes between assets in the money market. The script should optionally accept a list of assets and search for missing routes between these asset pairs.

Create a script that reads all money market assets and sets onchain routes

• only setting new routes to avoid resetting alreadt working good routes
• excluding HSM pool
• excluding where we have only one Omnipool hops, as no need to set that as thats the default

Output: TC proposal
