httprunner的env里，有空格和注释报错问题解决

.env

testenv=xxxxx

1.当文件内包含注释或空行时，抛出异常 httprunner.exceptions.FileFormatError: .env format error
原因是源代码中没有对空行和 # 号做处理，代码片段 (loader - 130)：

with open(dot_env_path, mode="rb") as fp:
    for line in fp:
        # maxsplit=1
        if b"=" in line:
            variable, value = line.split(b"=", 1)
        elif b":" in line:
            variable, value = line.split(b":", 1)
        else:
            raise exceptions.FileFormatError(".env format error")

2.加上判断忽略掉注释和空行，就不会报错了(源代码路径：httprunner-->loader.py)

with open(dot_env_path, mode="rb") as fp:
    for line in fp:
        # maxsplit=1
        line = line.strip()
        if not len(line) or line.startswith(b"#"):
            continue
        if b"=" in line:
            variable, value = line.split(b"=", 1)
        elif b":" in line:
            variable, value = line.split(b":", 1)
        else:
            raise exceptions.FileFormatError(".env format error")
