svelte-check should clear the output of previous runs instead of scrolling down

[ebeloded]

Describe the bug

svelte-check --watch retains the log output from previous runs (unlike, say, tsc --watch).

Reproduction

1. Run svelte-check --watch
2. Add an error
3. Remove an error
4. The history of previous runs is in place

Expected behaviour

The output should be cleared between outputs (unless used with --preserveWatchOutput flag)
