Fix multi-page CSV print DataError by using single print session

[3dberg]

Previously, each CSV row created a separate print session (printInit → printPage → waitForFinished → printEnd), causing DataError on subsequent pages because the printer wasn't ready to reinitialize immediately. Now uses a single session with the correct totalPages count, sending all pages before waiting.

It implements #76, If I understand correctly?

Tested with my printers. B21_C2B, B21_PRO, B1 - ok.
D110 - fails after first page.

after-pr.log

For this reason, I have not yet replaced the dumb printing method, as it is as compatible with most printers 😅

I will need to try multi-page printing with D110 in the official application and make a packet capture.

Having multiple options for the different models would be beneficial. For my M2, it works, but with the current single session, it fails on page 1. :)

Earlier, I added page delay option to deal with DataError

I will try to figure out the D110 printing error. I think it's time to start using the multi-page printing protocol functionality properly.

ok, seems the issue is not calling waitForFinished() after each page, everything else is ok

For D110 status is polled after each page, for newer models - when all pages are sent.

So, It require changes in niimbluelib.

Please make changes:

1. Switch your base branch to dev.
2. Update @mmote/niimbluelib to 0.0.1-alpha.37
3. Add currentPrintTask.printPage(encoded, quantity) call after currentPrintTask.waitForPageFinished() (in the page loop).

@3dberg Are you planning to make changes, or should I accept the PR as is and make the adjustments myself?
