don't add integers to string literals (#410) 
* string literal + integer means unintended and incorrect pointer arithmetic

fixes a clang warning. it could not be triggered, because it can only be
triggered if the string given to getopt is not covered among the
cases in the switch.

* handle review comment

output failed fuzz cases (#409) 
this is to get more debug output from cases like this:

The problem is that github actions does not store artifacts on failure.

Paul Dreik 8192e63a4b
update apt repos before installing (#408) 
This should hopefully resolve the recent errors in the github action
for running the fuzzers.

John Keiser 7d7bec856d Remove lookup_lower_4_bits 
It's only a coincidence that it works in current uses: it doesn't do
what the name says. Particularly, if the high bit is 1 it will yield
0 even if the lower 4 bits would yield something else.

Make threads optional in the cmake build (#376) 
Only the simdjson library should optionally depend on threads,
the executables that link to simdjson will get the dependency
indirectly.

* add option for controlling threads (default is on)

* fix an unrelated copy paste comment error in the cirlce ci build conf
