semver.satisfies is not working as expected

[DmitrySokolov]

Here is the output of semver.gte, semver.lt, semver.satisfies

20.12.1-0 gte 20.12.0-0 : True
20.12.1-0 lt  20.13.0-0 : True
20.12.1-0 >=20.12.0-0 <20.13.0-0 : False, expected True - failed

Test:

import semver

x = "20.12.0-0"
y = "20.13.0-0"
z = f">={x} <{y}"

for v in ["20.12.0-0","20.12.0-1","20.12.0","20.12.1-0","20.12.1-1","20.12.1","20.12.2-0","20.12.2-1","20.12.2","20.13.0-0","20.13.0-1","20.13.0"]:
    r1 = semver.gte(v, x, loose=True)
    r2 = semver.lt(v, y, loose=True)
    r3 = semver.satisfies(v, z)
    print(f"{v} gte {x} : {r1}")
    print(f"{v} lt  {y} : {r2}")
    print(f"{v} {z} : {r3}, expected {r1 and r2}{'' if (r1 and r2) == r3 else ' - failed'}")

if v >= min and v < max then satisfies should also return True.
