Improved table cell performances by putting all hooks from
RecordTableCell in RecordTableContext and RecordTable component, so that
each cell now only subscribes to a reference to those hooks' returned
function.
We couldn't do memoization here since the problem is not to memoize
between re-renders but to share the same function reference between
hundreds of different components, so a context it the fastest way for
this.
I had to refactor the hooks a little bit so that they take as arguments
what was previously taken from the cell's context.
