Describe the bug
Areas are misattributed to fuel consumption entity

To Reproduce

from quantulum3 import parser
print(parser.parse('I want 2 mm2 of gold leaf and 3 acres of land'))
print(parser.parse('I want 2 mm2 of gold leaf'))
print(parser.parse('I want 3 acres of land'))

Expected behaviour

[Quantity(2, "Unit(name="square millimetre", entity=Entity("area"), uri=None)"), Quantity(3, "Unit(name="acre", entity=Entity("area"), uri=Acre)")]
[Quantity(2, "Unit(name="square millimetre", entity=Entity("area"), uri=None)")]
[Quantity(3, "Unit(name="acre", entity=Entity("area"), uri=Acre)")]

Observed behaviour

[Quantity(2, "Unit(name="square millimetre", entity=Entity("area"), uri=None)"), Quantity(3, "Unit(name="acre", entity=Entity("area"), uri=Acre)")]
[Quantity(2, "Unit(name="square millimetre", entity=Entity("fuel consumption"), uri=None)")]
[Quantity(3, "Unit(name="acre", entity=Entity("area"), uri=Acre)")]
