GH-39 relax ofx response parsing to support TYPE1 responses

Browse Source 
Section 4.2.2.2 Type 1 Protocol Overview in the
[Open Financial Exchange Specification 2.2, Nov 26, 2017](https://www.ofx.net/downloads/OFX%202.2.pdf)
states that:

    Type 1 applies only to the request part of a message; the server response is unaffected.

Thus it appears that we can safely parse SECURITY:TYPE1
using the same logic that we parse SECURITY:NONE

As I understand it, Security:TYPE1 indicates that the
financial institution uses SSL enryption to protect
customer credentials in transit.  This applies
explicitly to the incoming requests which may
contain authentication as part of the request
but does not appear to cause any material changes
to the response format.

As a result it appears that we can safely parse
SECURITY:TYPE1 responess in the same way that
we parse SECURITY:NONE responsese.
