collisions on central progress file with standard tmpdir

[code-acrobat]

It's not possible to safely deploy with standard TMPDIR settings with multiple users as the progress file is shared.
With single users the output can be misleading, with multiple involved users you potentially get an error.
[exec] Error: EACCES: permission denied, open '/tmp/rollup-plugin-progress'

export TMPDIR=`mktemp -d`
$ nodejs
> const { default: os } = await import("os");
> path.resolve(os.tmpdir(), "./rollup-plugin-progress");
'/tmp/tmp.LZKCTrQUm2/rollup-plugin-progress'

Forcing users to change the shell defaults is very user unfriendly.

A better way would be to use the tmp module.

Hi @code-acrobat, I believe you're right. I never thought that this plugin would be used with multiple users on same machine at the same time. I would be happy to accept a PR for this issue and publish the new version to npm.
