Feature request: export to cadnano.json or custom sequence input

[HalseyWang]

Hello,

First of all, this tool is simply awesome, I am very happy to use it in combination with Cadnano and export large structures of oxdna! Thanks for open source for the community!

But one thing is that cadnano can customize the input of each sequence. This software cannot specify the input of the sequence, so the design of many large-scale structures assembled from single-stranded DNA still needs to be designed with cadnano. So, I have a feature request - it would be great if ENSnano files could be exported to Cadnano json format or custom DNA strand input sequences could be specified, which would be especially useful for both simulation and cadnano design.

thank you very much!
