Bump tape from 4.13.3 to 5.2.1 and pin run-parallel (#715)

- Bump `tape` devDependency from 4.13.3 to 5.2.1
- Avoid `t.throws()`, fails on errors with non-configurable message
- Pin `run-parallel` to 1.1.10 for browser compatibility. Later
  versions depend on `queue-microtask` which uses arrow functions
  and promises.
