This is just for me to understand how all this works, and to learn something new.

For example, I learned that endianness is not per bit but per byte. My whole life I've been in misinformation.
So little endian is not that first bit is the LSB, but it's MSB... and after 8 bits it becomes larger, which makes no point

And I learned about sign extension, which is pretty cool

And I learned that Java is bad because it doesn't have unsigned numbers

To compile stuff:
0. Get the toolchain obviously
1. riscv32-unknown-elf-gcc -c -Oz program.c
2. riscv32-unknown-elf-objcopy -O binary program.o program.bin
   program.bin is the binary file with the program
3. Encode to Base64: cat program.bin | base64

rv32i, ilp32 compatible toolchain for 64bit Linux: https://lfs.m724.eu/toolchain.tar.zst
Or just the stuff necessary to make a binary file: https://lfs.m724.eu/toolchainlite.tar.zst
Those were compiled with `./configure --prefix=$(pwd)/../toolchain --with-arch=rv32i --with-abi=ilp32` and `make`
