Created EconomicImpact class which is extendable to encompass different metrics

can be used as follows : 


from policyengine import EconomicImpact

impact = EconomicImpact(
    reform={"gov.hmrc.income_tax.rates.uk[0].rate": {"2024-01-01": 0.25}},
    country="uk"
)
result = impact.calculate("inequality/gini")
print(result)

result_top_1 = impact.calculate("inequality/top_1_pct_share")
print(result_top_1)

result_top_10 = impact.calculate("inequality/top_10_pct_share")
print(result_top_10)
