Add Connection Fracturing Statistics Summary Vectors

[bska]

This commit adds support for collecting and reporting the following set of connection level fracturing statistics measures

• CFR<Q>MAX – Maximum value of connection level fracturing quantity <Q>
• CFR<Q>MIN – Minimum value of connection level fracturing quantity <Q>
• CFR<Q>AVG – Arithmetic average of connection level fracturing quantity <Q>
• CFR<Q>STD – Unbiased standard deviation of connection level fracturing quantity <Q>

The currently supported quantities (<Q>) are

• P – Fracture pressure
• IR – Injection flow rate
• WD – Fracture width

These vectors adhere to the common connection level summary vector specification whence

CFRPMAX
  'I1' 16 16 6 /
/

CFRIRAVG
  'I1' * /
/

CFRWDSTD
  * * /
/

will report the maximum pressure across all cells intersected by a fracture originating in connection (16,16,6) of well I1, one average value for each connection of well I1 with the average being taken over all cells intersected by the fraction originating at that connection and, finally, the standard deviation of the fracture width for each connection of each well with each standard deviation being calculated over all cells intersected by the fracture originating at that connection.

I am creating this PR in a draft state for two reasons

1. It depends on, and contains, the earlier PR Add Infrastructure for Geomechanical Simulations and Formation Damage #4381.
2. The new data member data::Connection::fract must be properly populated, through downstream PR Report Connection Level Fracturing Statistics to I/O Layer opm-simulators#5811, before it is usable as a summary vector value backend.

I will keep the PR in draft mode until such time as it is ready for review.
