feat(mapper): expressions now have access to the Faker libary, rather than just faker instance

[Mac-lp3]

I made a post in the discussions about my motivation for this.

Note the Faker lib provides two ways to accomplish this:

1. How it is done in this PR

from faker import Faker
Faker.seed('something')
faker = Faker()

2. Create your faker instance using the Faker.factory() method.

from faker.factory import Factory
Faker = Factory.create
fake = Faker()
fake.seed(0)

Option 2 is actually what the faker docs recommend.

Unfortunately, option 2 does not allow for multiple locales. Given that, I thought it best to go with option 1, rather than breaking other people's code.
