mkinitcpio v29 came with zstd support (yay \o/), but the
default compression level is -19, which is horribly slow
even on my 12c/24t Zen 2.
Please consider lowering the compression level at least to -10. Thanks. |

Although in my opinion the compression level should not be preset in mkinitcpio, because zstd is meant for speed and -19 is a lot slower than gzip, even with -T0. Anyway, the proposed fix allows to override the default, whatever it is. So with the fix the default -19 can be kept.
