Specifying scan and copy performance options cause exceptions

[dabadab]

version: b803e3e commit

Specifying either --scan-threads, --scan-buffer, --scan-max-buffer or --copy-raw-zip results in the exception:

java.lang.NullPointerException: Cannot invoke "io.github.datromtool.cli.option.PerformanceOptions$ForceOptions.isForceUnrar()" because "this.forceOptions" is null

	at io.github.datromtool.cli.DatRomCommand.main(DatRomCommand.java:31)

If --force-unrar is also specified these exceptions do not appear.

Specifying --copy-threads causes a different exception that is not fixed by --force-unrar:
