Connecting LND wallet - invoice.macaroon is too permissive

[RocketNodeLN]

Is your feature request related to a problem? Please describe.
Currently need to provide pre-baked invoice.macaroon which includes the follwing permission:

"permissions": [
  "address:read",
  "address:write",
  "invoices:read",
  "invoices:write",
  "onchain:read"
]

Describe the solution you'd like
Accept custom baked macaroon with only invoices:write permission (example below) or pre-baked invoices.macaroon with this permission:

"permissions": [
  "invoices:read",
  "invoices:write"
]

Command to create a custom macaroon for stacker news
lncli bakemacaroon invoices:write --save_to ~/.lnd/data/chain/bitcoin/mainnet/stackernews.macaroon
