Scifi add version property for decoding

The Gaudi::Property DecodingVersion is added to FTRawBankDecoder. The user can now decide which decoding version is needed. In case the decoding version is not compatible with the version in the raw banks, an exception is thrown.

Fixes a problem introduced in MR !1326 (merged), which causes a crash for multithreading.

Requires a concurrent fix in the Brunel tests.
