fmt command panicked by throw statement

[srackham]

The snippet below compiles and runs but causes the fmt command to panic:

$ deno --version
deno 1.0.0
v8 8.4.300
typescript 3.9.2

$ cat deno-fmt-panic.ts 
try {
  throw new TypeError
}
catch {
}

$ deno run deno-fmt-panic.ts 
Compile file:///home/srackham/local/projects/drake/tmp/deno-fmt-panic.ts

$ deno fmt deno-fmt-panic.ts 
thread 'tokio-runtime-worker' panicked at 'Expected to find a close paren token.', /home/runner/work/deno/deno/.cargo_home/registry/src/github.com-1ecc6299db9ec823/dprint-plugin-typescript-0.17.2/src/parsing/parser_types.rs:787:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
thread 'main' panicked at 'Panic formatting: deno-fmt-panic.ts', cli/fmt.rs:232:5

Currently deno fmt panics on bad syntax like the above (new TypeError is invalid syntax as it is missing the parens), maybe it should raise one of the conformed errors.

It would be good to improve it not to panic in these scenarios. I'll look into this.
