Remove utls library from snowflake and use ptuil/utls
Since we are now going to be using utls
for conjure
(see conjure!30 (merged)), it makes sense to move theutls
library our of snowflake
and into ptutil
. This has already been merged into ptutil
with ptutil!4 (merged). This MR uses ptutil/utls
and removes common/utls
.
