Error when transferring big, really big strings about wampy

Hi @sergio-bershadsky

Sorry for the long delay responding to you. Many thanks for raising this.... and I knew this day would one day come!
wampy hasn't yet implemented messaging across multiple frames and I'm guessing that in your logs you can find this message: https://github.com/noisyboiler/wampy/blob/master/wampy/transports/websocket/frames.py#L135

I'm really pleased that you are using wampy, and I'm sorry that you have discovered this deficiency.

I'll be putting on my wampy hat again mid-July when I have some time off for the virtual EuroPython. Feel free to chip in with the required enhancement in the meantime, otherwise, I'm too busy with the day job to look at this now, sorry.

But it will be addressed.

Thanks again.

@sergio-bershadsky looking at sorting this out this coming week.
