Include Custom Endpoint option to solpg


Problem to Solve:

Currently, the Solana Playground only supports select endpoints provided in the drop down.

Often times the RPCs are down. Solpg helps us quickly fetch data in accounts from mainnet of a specific program. Since we can only use the RPCs in the dropdown, this one off quick testing actually compels the developer to write some script in local machine if the provided RPCs are not working.


Possible Solution:

Add a custom endpoint option - when RPCs are down then user should be able to put in his own RPC and continue using the tool.  In case existing provided rpc's are not working someone can make an account on Alchemy or QuickNode and use their own paid RPC.
