Allow setting name and modification date for literal data packet; BC …

[jdurani]

BC 1.77 and jdk8on:

• since BC jdk15on stopped with version 1.67 and there are still vulnerabilities, moved to jdk18on
• source and target compatibility is set to Java 8 anyway
• updated to latest version

New providers:

• in some cases, we need to set a name and/or modification date for a literal data packet in encrypted/signed file. This library is designed to work with stream, yet we can stream a file content...
• ... or, we can simulate file or need to set for whatever reason name of literal data
• this PR has two new functional interfaces to provide name and/or modification date
• default is to use current behavior (an empty string as a name "" and current date new Date() as a modification date)
• implemented in Build interface
