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
