Minesweeper test task

What was done

• Base game logic and basic ui
• Build configuration adapted from my pet project (https://github.com/saitonakamura/midi-explorer/tree/master/frontend)
• No fancy linters, only barebone ts and jest
• Basic tests for core logic
• Tailwind for styling
• Some basic ui components

What could be done better

• There's a bug in mines distribution, there's a chance amount won't be exact
• Core logic uses immutable appoarch which is great for debugging, but perfomance can be improved if we'll use mutable data
• Using single array (instead of native multidimensional arr[][]) on the other hand may be error prone and more cumbersome to support

Possible improvements

• Better overall design
• Win/lose screens that show mines locations
