Update TP has been deprecated in favour of Update Deal

[kand617]

It appears that Update TP has been deprecated:

https://github.com/3commas-io/3commas-official-api-docs/blob/master/deals_api.md#deprecated-update-take-profit-condition-deal-status-should-be-bought-permission-bots_write-security-signed

The new API uses update deal(deal_id)

Would you be able to add support for update deal endpoint?

@Amantel would you mind to have a look at this issue?

@kand617 please see issue #15 Would this method help to make a request for updated deal endpoint?

[Amantel]

@rentorm wow, I missed that message. I agree on #15 proposal, though.
