GP-253, GP-725 Gfilesystem ByteProviders, obfuscated temp files, passwords

Browse source 
Migrate GFilesystem methods to use ByteProviders instead of java Files for their source, and to produce ByteProviders instead of InputStreams.

Refactor file info query method to return a structured collection of enum specified meta data instead of a free-form multiline string.

Add locked icon badge to files in the file system browser that are password protected.

Reduces the number of temp files created on disk, and obfuscates files that are created to avoid the wrath of virus scanners (in the same manner that ghidra db files are obfuscated).

Add support for filesystems to query for passwords to decrypt files.

Refactor the SevenZipFileSystem implementation to decrypt files embedded inside zips that were created with passwords.

Fix Ext4 to support 128 byte inodes.
