It was created for internal use, and is not part of the context-store
public API. It was introduced as part of the "zip import" functionality
added in 291e86289b. Initially it was
[non-exported][1], but during review, some suggestions were made to improve
the implementation, and the [suggested implementation][2] was based on
Go stdlib, but review overlooked that the implementation was now exported.
Let's un-export it, as this was (as outlined) never meant to be a public
type.

Adds capabilities to import a .zip file with importZip.
Detects the content type of source by checking bytes & DetectContentType.
Adds LimitedReader reader, a fork of io.LimitedReader,
was needed for better error messaging instead of just getting back EOF.
We are using limited reader to avoid very big files causing memory issues.
Adds a new file size limit for context imports,
this limit is used for the main file for .zip & .tar and individual compressed
files for .zip.
Added TestImportZip that will check the import content type
Then will assert no err on Importing .zip file
