MIME does not allow binary data

[mwisnicki]

README says:

fun MIME(vararg mimeToData: Pair<String, Any>): MimeTypedResult 

which had me hoping I can pass binary data for non-text formats but the actual signature is:

fun MIME(vararg mimeToData: Pair<String, String>): MimeTypedResult

Passing PNG as ISO-8859-1 encoded String didn't work too.

We follow messaging protocol, and using this low-level API is in strict correlation with its documentation:
https://jupyter-client.readthedocs.io/en/stable/messaging.html#display-data

The fact that you have no visible result in browser is because jupyter-notebook client does not support image/png MIME type. You still can render images using text/html or use corresponding convenience methods
