invalid json log lines

[yakimant]

Describe the bug

"msg":"identify: decoded message","topics":"libp2p identify" lines are invalid sometimes

Makes parsing with jq more complicated, need to filter out the lines:

doneparse error: Invalid string: control characters from U+0000 through U+001F must be escaped at line 67749, column 2

or

parse error: Expected separator between values at line 161430, column 1
