This changes the file paths to use characters that are safe for Windows.
Channges the output of the following:
* Package cache directory
* Generated pkl-doc files
* Kotlin generated code
Unsafe characters are encoded as (<hex>).
For example, the colon character `:` is encoded as `(3a)`.
Additionally, this changes the cache directory prefix (package-1 to
package-2).
