Add new command `path:dig` which will excavate for you without adding any blocks.
`up|down` will dig a stair step passage (1 forward, and 1 up|down), `ahead` will dig straight ahead, and `vup|vdown` will dig straight up or down from 1 block in front of you.

For example, `path:dig down 20` will dig a stair step passage 20 blocks long going down 1 block at a time.

Additionally, this release supports **SILK_TOUCH** and **FORTUNE** when collecting material, and **UNBREAKING** when calculating tool damage. (_NOTE the calculations are not exactly the same as in regular Minecraft, but they are pretty close_).

Added new command /path:follow to create a path wherever the player walks.

Usage: `path:follow <start|stop> [radius] [path material]` (aliased as `pf`) where [radius] is a number between 0 and 5, and [path material] is any solid block. NOTE you must run path:follow stop to tell Pathinator to stop creating a path wherever you walk.

For example, `path:follow start` will start following using the default radius and whatever block you are currently standing on. `path:follow start 2 minecraft ak_planks` will create a wide path with OAK_PLANKS.

Updates CommandAPI to include support for 1.21.1.
