Helper functions for packing and unpacking tarfiles.

## Usage

```typescript
import { Tar } from "https://deno.hibas123.de/raw/@denreg-tar";

// The first parameter can be a file or a folder
await Tar.compress("test.txt", "test.tar");
await Tar.decompress("test.tar", ".");
```

Currently containes a version of the <https://deno.land/std/archive/tar.ts> library, but with a fix for subfolders.
