Add support for AWS textract

[MarkDirksen]

Hi,

I was wondering if there is any interest in adding support for AWS textract for extracting text / tables ? I noticed there is already an option for a similar offering from Azure (AzureConverter). I mainly use AWS and it would be convenient to use Textract instead.

If there is interest in doing so I might be able to spend some time on it in the near future. In that case I'll have some questions on the details.

Thanks!
