Subject: [PATCH] Use JSON.parse for parsing teambuilder tables

This optimizes JavaScript parsing performance. V8 developers
recommend applying this optimization for objects of 10 kB or
larger, see <https://v8.dev/blog/cost-of-javascript-2019#json>
for more details. Teambuilder tables are 3.5 MBs which is much
more than 10 kB.
