Add Sorting back to ViewRaid page

[nobrayner]

Previous Svelte version had a select to change the sorting of the ranking based on commits, additions, or deletions.

Currently no sort whatsoever has been applied. This should be added back in.

See the below for reference:

Lines 18 to 27 in 3367e37

	const userStatSorts: {
	[key: string]: (a: UserStats, b: UserStats) => number
	} = {
	commits: (a, b) => b.commits - a.commits,
	additions: (a, b) => b.additions - a.additions,
	deletions: (a, b) => b.deletions - a.deletions,
	}
	const userStatSortNames = Object.keys(userStatSorts)
	let currentSort = userStatSortNames[0]
