Incorrect check in adafruit_atecc_asn1.py:issuer_or_subject_length

[brass75]

In the issuer_or_subject_length function there is a check for the presence of one of the parameters where the check should really be that at least one parameter was passed with a value:

def issuer_or_subject_length(country, state_prov, city, org, org_unit, common):
    """Returns total length of provided certificate information."""
    tot_len = 0
    if country:
        tot_len += 11 + len(country)
    if state_prov:
        tot_len += 11 + len(state_prov)
    if city:
        tot_len += 11 + len(city)
    if org:
        tot_len += 11 + len(org)
    if org_unit:
        tot_len += 11 + len(org_unit)
    if common:
        tot_len += 11 + len(common)
    else:
        raise TypeError("Provided length must be > 0")
    return tot_len

The else on the bottom should be changed to if not tot_len or the equivalent.
