A description of the changes proposed in the pull request:

• removes near and xrpl chain connectors
• removes xrpl and dexalot DEX connectors since they are now built into Hummingbot
• removes ref and perp DEX connectors due to Epoch 8 governance
• removes PerpAmm, CLOBSpot and CLOBPerp routes and classes

Note that this change removes kujira chain and DEX connectors since it is a CLOB connector, which are only supported in the Hummingbot client.
