This is another year of puzzles, this time in kotlin

• When calculating a position of a text on screen, make sure the text is monospaced...
• coerceIn. given a number get the closest number in a provided range (day9)
• Kotlin does now throw an overflow when you calculate an Int over it's MAX_VALUE... (day11)
• When generating a bunch of values, that we don't really need to store permanently. Use a sequence (day15)
