FRE-600: Fix code review blockers

- Consolidated duplicate UndoManagers to single instance
- Fixed connection promise to only resolve on 'connected' status
- Fixed WebSocketProvider import (WebsocketProvider)
- Added proper doc.destroy() cleanup
- Renamed isPresenceInitialized property to avoid conflict

+
+Fast base encoding / decoding of any given alphabet using bitcoin style leading
+zero compression.
+
+**WARNING:** This module is **NOT RFC3548** compliant,  it cannot be used for base16 (hex), base32, or base64 encoding in a standards compliant manner. 
+
+## Example
+
+Base58
+
+``` javascript
+var BASE58 = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'
+import basex from 'base-x'
+var bs58 = basex(BASE58)
+
+var decoded = bs58.decode('5Kd3NBUAdUnhyzenEwVLy9pBKxSwXvE9FMPyR4UKZvpe6E3AgLr')
+
+console.log(decoded)
+// => Uint8Array(33) [
+//   128, 237, 219, 220,  17, 104, 241, 218,
+//   234, 219, 211, 228,  76,  30,  63, 143,
+//    90,  40,  76,  32,  41, 247, 138, 210,
+//   106, 249, 133, 131, 164, 153, 222,  91,
+//    25
+// ]
+
+console.log(bs58.encode(decoded))
+// => 5Kd3NBUAdUnhyzenEwVLy9pBKxSwXvE9FMPyR4UKZvpe6E3AgLr
+```
+
+### Alphabets
+
+See below for a list of commonly recognized alphabets, and their respective base.
+
+Base | Alphabet
+------------- | -------------
+2 | `01`
+8 | `01234567`
+11 | `0123456789a`
+16 | `0123456789abcdef`
+32 | `0123456789ABCDEFGHJKMNPQRSTVWXYZ`
+32 | `ybndrfg8ejkmcpqxot1uwisza345h769` (z-base-32)
+36 | `0123456789abcdefghijklmnopqrstuvwxyz`
+58 | `123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz`
+62 | `0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ`
+64 | `ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/`
+67 | `ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_.!~`
+
+
+## How it works
+
+It encodes octet arrays by doing long divisions on all significant digits in the
+array, creating a representation of that number in the new base. Then for every
+leading zero in the input (not significant as a number) it will encode as a
+single leader character. This is the first in the alphabet and will decode as 8
+bits. The other characters depend upon the base. For example, a base58 alphabet
+packs roughly 5.858 bits per character.
+
+This means the encoded string 000f (using a base16, 0-f alphabet) will actually decode
+to 4 bytes unlike a canonical hex encoding which uniformly packs 4 bits into each
+character.
+
+While unusual, this does mean that no padding is required and it works for bases
+like 43. 
+
+
+## LICENSE [MIT](LICENSE)
+A direct derivation of the base58 implementation from [`bitcoin/bitcoin`](https://github.com/bitcoin/bitcoin/blob/f1e2f2a85962c1664e4e55471061af0eaa798d40/src/base58.cpp),  generalized for variable length alphabets.
