BHoM_Engine: inconsistency in what is considered BHoM namespaces

[pawelbaran]

Description:

In different parts of reflection, some namespaces are considered valid BHoM or not:

• core reflection method ExtractAssembly is checking namespaces against Regex patterns: https://github.com/BHoM/BHoM_Engine/blob/7cb0fb17ea012daeace6cdc6b8b500693c8ffcf0/BHoM_Engine/Compute/ExtractAssembly.cs#L281-L282
• meanwhile, .Create.AllTypes in BHoM_Engine: https://github.com/BHoM/BHoM_Engine/blob/7cb0fb17ea012daeace6cdc6b8b500693c8ffcf0/BHoM_Engine/Create/Type/AllTypes.cs#L50-L56
• meanwhile Serialiser_Engine has hardcoded StartsWith queries: https://github.com/BHoM/BHoM_Engine/blob/7cb0fb17ea012daeace6cdc6b8b500693c8ffcf0/Serialiser_Engine/Compute/Serialise/Type.cs#L91 https://github.com/BHoM/BHoM_Engine/blob/7cb0fb17ea012daeace6cdc6b8b500693c8ffcf0/Serialiser_Engine/Compute/Deserialise/Type.cs#L148

The above inconsistency introduces idiosyncrasies in some more complex reflection/serialisation workflows - would be great to unify across the entire code base.
