Serialize multiple vcard generate wrong start/end frame

[rallets]

Hi, I'm serializing multiple vcards, and the Start/End frame is generated on the same line, breaking the import in Android.
Basically it generates a vard that looks like

[...]
GENDER:None
END:VCARDBEGIN:VCARD
VERSION:3.0
[...]

but I'm expecting

[...]
GENDER:None
END:VCARD
BEGIN:VCARD
VERSION:3.0
[...]

Any tips?
Thank you

@bolorundurowb I have sent a PR to fix these two issues, with related unit tests, could you take a look? are you interested in merging them?
Thank you

Approved the PR, but there is a failing test due to the line endings \r and the test runner expecting \r\n. You can replace the line endings in your string with Envrionment.NewLine

@bolorundurowb I updated the PR and it looks the tests are passing now. Can you merge and generate a new release?
Thank you!
