Inso CLI does not support multipart form structure in requests

[andressalro]

Is your feature request related to a problem? Please describe.
I need to automate the unit test of an endpoint that uploads a file to the server. I wanted to use Inso CLI for this purpose but I realized that it doesn't seem to support requests with a multipart Form structure.

Describe the solution you'd like
The solution that meets my need is for Inso CLI to allow testing of endpoints that need the multipart form structure and also to allow uploading files to the server. This in order to automatically test the uploading of files.

Describe alternatives you've considered

Additional context
If you make a request with the multipart form structure, whether or not you send a file, you will get a timeout error in the console. I thought it did not support files, but with this test I realized that it does not support the multipart form structure.
