Symantec VIP Access Token support

Symantec has created their own TOTP that should be possible to convert to generic TOTP, but these instructions are not something an average user can be expected to follow. It would be great if Bitwarden could have some specifier such as SYMC:// that would do the needed when adding these time-based one time passwords.

Arguably Symantec VIP is not very widely used, but there are enough web sites using this technology that I think it would make sense to add this feature. Point of the feature is provide the usual Bitwarden benefits to these SYMC TOTPs - one does not want to manage separate authentication applications on phone, or have complicated backup credentials in case of losing a phone.
