Merge #19287: contrib: Fix SyntaxWarning in Python base58 implementation

47b49a05eafddcaef373f70436d794e9f9f7495c contrib: Fix SyntaxWarning in Python base58 implementation (Alex Willmer)

Pull request description:

  In Python integers should be compared for equality (`i == j`), not identity (`i is j`). Recent versions of CPython 3.x emit a SyntaxWarning when they encounter this incorrect usage, e.g.

  ```
  $ python3 base58.py
  base58.py:110: SyntaxWarning: "is" with a literal. Did you mean "=="?
    assert get_bcaddress_version('15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC') is 0
  Tests passed
  ```
