Code quality stuff

Use the same namespacing style everywhere, that being nn_<class>_<method> for functions related to "classes", nn_<function> for static functions, nn_<type>_t for types.
Rework to API to be much more future-proof to reduce potential breaking changes.

Parity with Vanilla OC (only the stuff that makes sense for an emulator)

hologram component
computer component
data component (with error correction codes and maybe synthesizing audio)
redstone component
internet component
computer.getDeviceInfo(), and subsequently, component device information
computer.beep(frequency?: number, duration?: number, volume?: number), frequency between 20 and 2000 Hz, duration up to 5 seconds, volume from 0 to 1.

Do a huge audit at some point
nn_unicode_charWidth appears to be bugged, look into that.
validate against moving a/b into a or moving a into a/b in the filesystem component.

oled component (OLED screen, a store of draw commands and resolution from NN's perspective)
ipu component, an Image Processing Unit. Can bind with oleds, and issues said draw commands
vt, a virtual terminal with ANSI-like escapes. (and a function to get its resolution)
(maybe) qpu component, a Quantum Processing Unit for quantum computing
radio_controller and radio_tower components, for radio telecommunications
(maybe) clock component for arbitrary precision time-keeping
led component for LED matrixes and/or LED lights
speaker component, allows playing audio by asking for binary samples and pushing a signal when it needs more
microphone component, allows reading audio from nearby sources
tape_drive component, compatible with Computronics, except maybe with proper seek times and support for multiple tapes
cd_reader and cd_writer components, to work with CDs
serial component, for serial communications with other devices (USB?)

make sure OOMs are recoverable
rework some interfaces to use pre-allocated or stack-allocated memory more
use dynamic arrays for signals (and maybe components), but still keep the maximums to prevent memory hogging
setup an extensive testing system to find bugs easier
use compiler hints to let the optimizer make the code even faster
