In this environment it's not feasible, or at least it's not documented
how, to distribute JavaScript code by packaging it as a wheel; only
Wasm code (as shared objects) can be distributed this way. The current
`amaranth-yosys` strategy would not work even though wheels can be
installed on Pyodide, and Yosys will need to be explicitly provided by
the environment instead.
The implementation is sufficiently generic that non-Pyodide hosts could
potentially make use of it, though it doesn't seem like any exist at
the moment.
