Bulk update/create Resources from Excel

Functionality: a means to allow admins to bulk update/create resources from excel.

Example:

1. ./tg export - by default, exports the admin's tenant into an xlsx file
2. The admin can go in and adjust most (see limitations below) cells for bulk configuration changes, and save the file.
3. ./tg import -f <xlsx-file> - will import the saved configuration changes and attempt to either (a) update the existing resource or (b) create a new resource

Explanation of changes:

TwingateApiClient.mjs:

• Expanded resource fields - although groups and serviceAccounts is now deprecated for the access connection, there doesn't seem to be consistency across the API so I left as is (FRs that need to be requested below).
• Updated createResource() for expanded functionality with the mutation
• Created updateResource() to allow bulk update functionality with the mutation

smallUtilFuncs.mjs:

• readerFromStreamReader seems to be deprecated, temporarily updated module to the last working version (not familiar enough with a path forward - @chenbishop?)
• updated genFileNameFromNetworkName() to accommodate new output folder so import/export files aren't dropped in main directory

importCmd.mjs:

• expanded functionality to support new updateResource()
• expanded functionality to support updated createResource()
• Added an outputDir so import files aren't dropped in main directory

exportCmd.mjs:

• Added an outputDir so export files aren't dropped in main directory

Instructions/Limitations & FRs needed:

Instructions/Limitations:

• Creating a resource:
  • A resource will be created if an existing Id is not found AND must have (a) name, (b) remoteNetworkLabel, and (c) addressValue specified.
    - serviceAccounts will not get updated as there is currently no argument available for resourceCreate mutation.
    - isActive will not get updated as there is currently no argument available for resourceCreate.
• Updating a resource:
  • A resource will instead be updated if an existing Id is found AND (a) name, (b) remoteNetworkLabel, and (c) addressValue are specified.
    - serviceAccounts will not get updated as there is currently no argument available for resourceUpdate.

FRs needed:

• resourceUpdate Mutation
  • needs serviceAccounts ([]) - or the new access{serviceAccounts, groupIds}
• resourceCreate Mutation
  • needs isActive (boolean)
  • needs serviceAccounts ([]) - or goes off the new access{serviceAccounts, groupIds}
