Add support to read a BP5 dataset / TEXT / IMAGE from TAR files...

[pnorbert]

... if provided with a detailed index (name,offset,size;...) for all metadata and data files. Used for supporting TAR files added to Campaigns with a tar index. For now it supports reading BP5 files and TEXT/IMAGE from

• a TAR file on local disk
• a TAR file on an HTTPS server
• a remote TAR file accessible by adios2_remote_server

OpenFileTransport() expected Params to be all lower case, now it does it on its own since BP5 is calling it directly.

My current read test commands for a handmade collection of campaigns:
