Financial data

[ParamConstructor]

Proposed changes

This is the PYCTI changes required to support the OpenCTI PR - https://github.com/OpenCTI-Platform/opencti/pull/5287

• Add new observables: Financial Accounts, Financial Assets, and Financial Transactions
• Add new vocabularies: financial_account_status, financial_account_type, asset_type, currency_code
• Removed BankAccount and CryptoWallet observables (migrated to Financial Account in OpenCTI)
• Add relation support for new observables

Related issues

• This needs to be deployed in tandem with the OpenCTI PR
• We have tested locally using unit tests / pytest locally - but the automated pipeline has not been used due to it checking out "master" on OpenCTI branch versus the equivalent "financial_data" branch
