My attempt to solve Advent of Code, this time using only F#!

I'm aiming for concise and succinct code. If it's short and readable, I'm happy, but I will also keep track of execution times as measured on my machine (AMD Ryzen 5 3500X; 16 GB DDR4).

Execution time is measured with F#'s #time construct surrounding the relevant code for each part. If some input parsing is done and it is reused for both parts, it'll be included as part of Part 1 execution.

Day	Link	Execution Time
01 Part 1	day01	2ms
01 Part 2		63ms
02 Part 1	day02	247ms
02 Part 2		6384ms
03 Part 1	day03	12ms
03 Part 2		11ms
04 Part 1	day04	54ms
04 Part 2		1114ms
05 Part 1	day05	77ms
05 Part 2		4ms
06 Part 1	day06	15ms
06 Part 2		15ms
07 Part 1	day07	43ms
07 Part 2		30ms
08 Part 1	day08	1383ms
08 Part 2		1352ms
