fix!: change default pool name to pgo_default

[tsloughter]

To have some backwards compatibility the use of default as the pool name is not allowed. Instead any use of default will be converted to pgo_default when the pgo module functions are in use.

Only took 3 years to fix #60 :)

@benbro @lpil any thoughts on my hack of backwards compatibility?

[lpil]

I would publish a new major version and not worry about backwards compatibility.

[tsloughter]

Yea, maybe I should just do that and also include the breaking change on arrays and/or json.

[benbro]

I don't mind backward compatibility in this case.
Thank you for the fix.

[lpil]

I don't think backwards compatibility is possible here. There is nothing stopping people from having used the name in their code.

[tsloughter]

yea, I'm thinking I'll remove the hack and end up releasing 1.0 once I decide on how to handle array and json values (will be soon).
