Discussion
This removes all accumulated text and resets the writer to its initial state (at line start). The indentation level is preserved.
Example
await writer.writeLine("Line 1")
await writer.clear()
let content = await writer.getContent()
print(content) // "" (empty)
await writer.writeLine("New start")
let newContent = await writer.getContent()
print(newContent) // "New start\n"
