Describe the bug

When trying to run licensecheck after installing and installing poetry the module crashes after call:

(venv311) PS C:\Users\steve\PycharmProjects\Parcival> licensecheck                
An error occurred with poetry, try running 'poetry show' to see what went wrong! - (fall back to requirements)
Traceback (most recent call last):

    myLice = license_matrix.licenseType(myLiceTxt)[0]
             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range

Tryin to run 'poetry show' as recommendet i get:

(venv311) PS C:\Users\steve\PycharmProjects\Parcival> poetry show

Poetry could not find a pyproject.toml file in C:\Users\steve\PycharmProjects\Parcival or its parents

falling back to requirements as hinted also prompts the same error

(venv311) PS C:\Users\steve\PycharmProjects\Parcival> licensecheck -u requirements
Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main

    myLice = license_matrix.licenseType(myLiceTxt)[0]
             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range

Expected outcome

Getting the list of licenses or a more helpful ErrorMessage

Actual outcome

An IndexError crashing the module

Getting the same with the latest version (2023.1.4).
For me adding a [project] section (even an empty one) to my project's pyproject.toml provided a good workaround.

fixed in 2023.2
