Fix exponential retries on parsing error

[moritz157]

This should fix #38 as it cancels the stream subscriptions if the message parser cannot parse a line. Also it catches responses without the header content-type: text/event-stream early and (if no response header connection: keep-alive is present) logs their body for debugging purposes.

Thank you @moritz157 for tackling this. I'm running into the same issue.

@pratikbaid3 what do you think of this approach? Is this ready for merging?

Hi @moritz157. Thank you for the PR. Looks good to merge. Doing some final testings to go ahead with the final merge.
