feat(memmap): add summary command to memory map script
This patch adds a `summary` command, invoked with:
poetry run memory summary <map-file>
This command is capable of producing a summary table, similar to the
footprint command, or an HTML flame-graph representing the size of ELF
image sections.
When specified with `-o` (`--old`), an old GNU map file is used as a
past state and subtracted from the GNU map file specified by
`<map-file>` to annotate printed information with additional size
deltas.
Note that many bootloaders include alignment padding and will align to
a page size. To exclude this alignment-padding from the summary, use the
`-e` switch.
For example:
$ poetry run memory summary bl1.map -e -d 1

refactor(memmap)!: change behavioural flags to commands
This change factors out the following memory map tool flags into
independent commands:
- `--footprint` (becomes `memory footprint`)
- `--tree` (becomes `memory tree`)
- `--symbol` (becomes `memory symbol`)
So, for example, where previously you would generate the memory
footprint of a build with:
memory --tree
You would now instead use:
memory footprint
Any flags specific to a command (e.g. `--depth` for `tree`) must be
specified after the command, e.g.
memory tree --depth 1
... instead of:
memory --depth 1 tree
BREAKING-CHANGE: The image memory map visualization tool now uses
commands, rather than arguments, to determine the behaviour of the
script. See the commit message for further details.

This change introduces Pyright - a static type checker for Python - and
resolves a large number of the errors that it reports. Some errors have
not been resolved as they require larger refactors, so these will be
done in later patches.

refactor(memmap): represent image symbols with key-value map
The symbols defined by an image are currently returned as a list of
tuple pairs, which is a fairly unintuitive way of representing what is
essentially a map.
This commit changes the return type to the appropriate map type, and
moves the heavy-lifting required to turn it into a list of tuples into
the printer, which is the only place where this representation is
necessary.

refactor(memmap): factor memory regions into their own structure
This is a non-functional change to clean up how we represent memory
regions in the memory map tool.
This introduces the `Region` data-class, which does little more than
store the region data exposed by the linker scripts, and provides some
additional helper methods which re-produce what was already being done
by both the ELF parser and the map file parser.
