Adding Transport Override for PDF use case

[haislip]

#97

In order to save the PDF generated from the APIs properly, the transport passed into the popsicle API needs to be one of type "buffer" instead of "text" (which is the default). This changes keeps the default of using "text", but allows the calling function to pass in the override.

Thanks, @haislip for the contribution. This PR will go in our next release.

hi @abisalehalliprasan

Any idea when this will be published over npm? Seems like you merged it but i think it's not published yet.

The /pdf route is broken until this is pushed to NPM. Not that I'm part of the dev team, but I just reviewed and verified it and it looks good, and there is currently no non-patching workaround to this afaik.

@sdegutis : Just curious what is the transport that you passed to the makeApiCall method ?

Would it be similar to :

oauthClient
    .makeApiCall({ url: `${url}v3/company/${companyID}/invoice/${invoiceNumber}/pdf?minorversion=59` , transport: popsicle.createTransport({type: "buffer"})})

Yep

I get a server error. wondering if the transport parameter that I have passed is correct :

@sdegutis : I did not pass the Accept header also as application/pdf

.makeApiCall({ url: `${url}v3/company/${companyID}/invoice/2/pdf?minorversion=59` , headers:{'Content-Type': 'application/pdf','Accept':'application/pdf'}, transport: popsicle.createTransport({type: 'buffer'})})

This returns a binary BLOB for the pdf response. Thanks for your help. I am good here 👍
