Implement attachment resizing on uploads

[dubdabasoduba]

Describe the feature request.

• The SDK allows image attachments via the SDC library here
• These attachments have a limit of max 5MB size.
• Due to the advancements in camera technology most cameras would take photos or videos larger than this size.
• This ticket is for us to implement a resizing strategy to make sure we can store these attachments in a usable manner.

Additional context

• This documentation here shows how much the size can be reduced if we convert the images to .webp versions
• [FHIR Road Map]: Implement Attachment resizing on uploads onaio/fhir-web#1483

Acceptance criteria

• Resize all attachments before converting them to Binary and saving them.
• All max attachment sizes should be adhered to.
