[Bug] Unable to load custom system template

[JasonLo]

I installed fructorse==0.0.11 from pip and ran the followings:

ai = Fructose(model="gpt-3.5-turbo")
@ai(system_template_path="custom_sys_prompt.jinja")  # template file is in the same directory
def generate(text: str) -> list[str]:
    """genearte some words."""
    ...

this error occur:

---------------------------------------------------------------------------
TemplateNotFound                          Traceback (most recent call last)

    206         with open(filename, encoding=self.encoding) as f:

TemplateNotFound: custom_sys_prompt.jinja

I believe the loader specifies the path to the installed package, not the current working directory. Could this be the cause of the problem?
