Keep escape backslash for newline/tab characters. Parsing still
differs from shell syntax but keeps string structure intact.
Example certificate data
VAR="---BEGIN---\r\n---END---"
now becomes
"---BEGIN---\r\n---END---"
instead of
"---BEGIN---rn---END---"

Change parsing of quoted strings to not remove \ before \r, \n and \t to allow basic formatting and certificate serializing.
Also include optional \r in delimiter when splitting string to multiple lines for better compatibility with PEM-certificates and MIME-headers
Example certificate data
VAR="---BEGIN---\r\n---END---"now becomes
r"---BEGIN---\r\n---END---"instead of
r"---BEGIN---rn---END---"This makes linebreaks work correctly with Env().str('VAR', multiline=True) as well
