checksums are frequently calculated together (see Dependency constructor) so it makes sense to only read files once to calculate all checksums together
use the already existing checksum methods instead

Fixes Issue
I noticed checksums can be very slow to calculate for some larger files. One of the reasons is that the file is read 3 times - once per each checksum. (See
Dependency.calculateChecksums(File).) This is easy to optimize by reading the file only once and calculating all 3 checksums together.Description of Change
There are two commits:

No new functionality added, and existing tests already cover the changed functionality.
