TCF v2.3: Unable to encode additional segments (e.g., vendorsDisclosed) when isServiceSpecific=true

[Lokesh-Singh-WBD]

When encoding TCF v2.3 with isServiceSpecific=true, the GPP Java encoder only allows one additional segment to the core segments. This makes it impossible to include additional valid segments as needed in our requirements. This functionality is not documented in the GPP specification.

Expected
Support encoding additional TCF v2.3 segments (disclosedVendors) regardless of isServiceSpecific.
Actual
Only one additional segment can be added with the core segment when isServiceSpecific as true; more than one additional segments is blocked.

Code Reference
Segment restriction appears here:

Question
Is restricting segments under isServiceSpecific=true intentional? If not, can segment extension be enabled?

This is not intentional or expected so it should be fixed. @chuff can you take a look at this?
