config: Change fee amount or fee structure for anchors

[mustermeiszer]

Description

Currently, the onchain fee structure for anchors is too heavy, i.e. taking too much CFG for anchoring documents.

• Mainnet: Feekey::Commit - 1 CFG → but that is multiplied with a factor onchain making it way to heay
• Also pay fees to treasury instead of author:

  centrifuge-chain/pallets/anchors/src/lib.rs

  Line 345 in d3a0f0c

  // TODO(dev): move the fee to treasury account once its integrated instead of

Solution A

• Change the onchain fee amount to a lower value

Solution B

• Change the onchain code to have a simpler anchor logic → Anyways needed for data protocol v1

Research/based on

• Testing in demo
