Update facet-cut-params-generator to handle add and replace selectors dynamically

[GitGuru7]

Description

This PR updates the facet-cut-params-generator script to improve how diamond cut parameters are generated:

• The script now fetches the current function selectors from the deployed diamond contract.

• It generates the final cut-params array, considering both Add and Replace operations dynamically.

• For IFacetBase selectors:

  • If there are no new selectors, the resulting cut-params JSON can be used directly.
  • If there are new selectors, they need to be manually assigned to the appropriate facet addresses before using the cut-params.

  Note: Now onwards when running the script, please use the --network flag to specify the target network.
