ASEM000/PyTreeClass: v0.3.4

• Exposed internal Partial (used for bcmap) for jaxable partial functions with positional arguments support

      >>> import pytreeclass as pytc
      >>> def f(a, b, c):
      ...     print(f"a: {a}, b: {b}, c: {c}")
      ...     return a + b + c

      >>> # positional arguments using `...` placeholder
      >>> f_a = pytc.Partial(f, ..., 2, 3)
      >>> f_a(1)
      a: 1, b: 2, c: 3
