Feature: [supertask runtime estimation] support the remaining hashcat attack types

[SherlockNL]

Recently a pull request has been opened for supertask runtime estimation on the supertask detail page: https://github.com/s3inlc/hashtopolis/pull/696

Currently, only -a0 and -a3 hashcat attacks are supported in this feature.

It would be great to have more attack modes supported. Continuing on the current code base, -a1 would be easiest to implement, although -a6 and -a7 are also not too difficult.
