Subject: blaze822: blaze822/blaze822_mem: detect line ending before scanning
 end of header

A mail using CRLF which contained (for some reason) a LFLF pair would
be misparsed as the header was read until the LFLF.

Instead, scan for the first LF, check if it's preceded by CR,
and then search for the proper header terminator only.

Closes #212.
