Make errors easier to read

Currently, errors generated by Wax that are not directly handled by try/catch - only showing their message - can take the entire buffer of the console and decrease end-user experience by showing a block of irrelevant whitespace.

A possible solution would be to remove terser from the Wax rollup configuration and wrap all the WASM calls in our custom try/catches.

We could also ensure all of the errors from internal Wax functions are derived from the WaxError.
