When building E-ARK SIPs with large files (such as MKV video files from moving image archives), the current implementation always calculates checksums during the write process, even when checksums are already known and set on the IPFile object.
The IPFile class already has setChecksum() and setChecksumAlgorithm() methods, but these values are never used during SIP generation. Instead, checksums are always recalculated in:
ZIPUtils.zip() - calculates checksum while zipping filesFolderWriteStrategy.writeFileToPath() - calculates checksum while copying files
