Parse Insomnia templates during import

[LucasPickering]

Insomnia has template-like strings that provide similar functionality to chains. It'd be nice to parse these and convert them to chains during import. This would be pretty complex though. Here's an example of a request with a template:

{
  "_id": "req_30f68ae3069b4ec59707bf793a4b74cb",
  "parentId": "fld_2b83df7de20d446f91d94dcb0b66c06f",
  "modified": 1712668874211,
  "created": 1710623967061,
  "url": "https://httpbin.org/get",
  "name": "Bearer Auth",
  "description": "",
  "method": "GET",
  "body": {},
  "parameters": [],
  "headers": [
    {
      "name": "User-Agent",
      "value": "insomnia/8.6.1"
    }
  ],
  "authentication": {
    "type": "bearer",
    "token": " {% response 'body', 'req_3bc2de939f1a4d1ebc00835cbefd6b5d', 'b64::JC5oZWFkZXJzLkhvc3Q=::46b', 'when-expired', 60 %}"
  },
  "metaSortKey": -1712668874167,
  "isPrivate": false,
  "pathParameters": [],
  "settingStoreCookies": true,
  "settingSendCookies": true,
  "settingDisableRenderRequestBody": false,
  "settingEncodeUrl": true,
  "settingRebuildPath": true,
  "settingFollowRedirects": "global",
  "_type": "request"
},

This could be converted to something like:

chains:
# This ID would have to be auto-generated somehow
  req_30f68ae3069b4ec59707bf793a4b74cb_authentication_token:
    source: !request
      recipe: req_3bc2de939f1a4d1ebc00835cbefd6b5d
      trigger: !expire 60s
    sensitive: true
    selector: $.headers.Host # This is decoded from the base64 content

requests:
  req_3bc2de939f1a4d1ebc00835cbefd6b5d: !request
    name: Login
    method: POST
    url: https://httpbin.org/anything/login
    body: null
    authentication: null
    query: {}
    headers: {}

  req_30f68ae3069b4ec59707bf793a4b74cb: !request
    name: Bearer Auth
    method: GET
    url: https://httpbin.org/get
    body: null
    authentication: !bearer "{{chains.req_30f68ae3069b4ec59707bf793a4b74cb_authentication_token}}"
    query: {}
    headers: {}

The Slumber collection we come up with is still pretty ugly, so not sure if this is worth the effort. I'm sure there's a ton of different settings in Insomnia we'd have to support too.
