Rdwv

Added missing event and history() fixes

This bugfix fixes xpub sending, and exception raising.

Structural improvements and more

Structural improvements

This version makes async version the default one used in the repo.

Pypi versions aren't changed, rdwv is sync version, rdwv-async is async.

But now there is a major difference, instead of maintaining both sync and async versions,
async version is in master, and sync version is generated using `sync_generator.py`, which basically removes async's and awaits.

It means less time spent, and instead of porting new features to sync/async versions, now I will have more time spend on new features!

The async branch will be deleted.

Sending transactions improvements

Also, the long awaited `pay_to_many` function to do batch transactions is there!
Both `pay_to` and `pay_to_many` now have optional `feerate`, which is sat/vbyte rate.

Minimum possible is 1 sat/vbyte.

With rdwv you can get minimal fees, with no third parties!

Added support for both args and kwargs, fixes
This version allows using SDK with both positional and by-name arguments.

Added missing pay_to_many

This release adds ability to create batch transactions, some examples:

python
>>> btc.pay_to_many([{"address":"mkHS9ne12qx9pS9VojpwU5xtRd4T7X7ZUt","amount":0.001}, {"address":"mv4rnyY3Su5gjcDNzbMLKBQkBicCtHUtFB","amount":0.0001}])

>>> btc.pay_to_many([("mkHS9ne12qx9pS9VojpwU5xtRd4T7X7ZUt",0.001),("mv4rnyY3Su5gjcDNzbMLKBQkBicCtHUtFB",0.0001)])
'd80f14e20af2ceaa43a8b7e15402d420246d39e235d87874f929977fb0b1cab8'

>>> btc.pay_to_many([("mkHS9ne12qx9pS9VojpwU5xtRd4T7X7ZUt",0.001), ("mv4rnyY3Su5gjcDNzbMLKBQkBicCtHUtFB",0.0001)], broadcast=False)
