dde9c0adbf Update to RC version of clap
Deriving a parser has become an opt-in feature so we need to enable
that.

e0e1bc26e8 Simplify implementation day 8
The second part doesn't actually need to start the search at the low
points; just iterating everything and keeping track of visited spaces is
enough.

Now that the iterator is only used in part 1, we inline the iterator to
remove some overhead from the code.

The state of a seven segment display can be stored in a byte after all.
Using NonZeroU8 makes the Options smaller too.

Nom is really nice and fast, why did I write parsers manually before.

392aefb32d Less allocations in day 3 part 2
By working with binary numbers as integers rather than byte strings, we
don't need to allocate a Vec for each of them, reducing us to just the
allocations in the outer Vec.

938eda0d22 Rework day 1
Simplify part 2 a lot, by not actually computing the sums because they
do not matter, only the changes do. Also eliminate the allocation
overhead while parsing line-by-line input.

Fixes the existing clippy error because the offending line no longer
exists.
