📄 Description

I took the liberty of upgrading the microPython version to 1.18.
According to the changelog:

This release of MicroPython sees a boost to the overall performance of the
VM and runtime.  This is achieved by the addition of an optional cache to
speed up general hash table lookups, as well as a fast path in the VM for
the LOAD_ATTR opcode on instance types.  The new configuration options are
MICROPY_OPT_MAP_LOOKUP_CACHE and MICROPY_OPT_LOAD_ATTR_FAST_PATH.  As part
of this improvement the MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE option has
been removed, which provided a similar map caching mechanism but with the
cache stored in the bytecode, which made it not useful on bare metal ports.
The new mechanism is measured to be at least as good as the old one,
applies to more map lookups, has a constant RAM overhead, and applies to
native code as well as bytecode.

I'm unsure if these are applied by default, but I'm open to someone reviewing this commit to enable any optimizations that would be nice to have.

Yes, it does compile and function. See below:
