Pulling in changes from @jkshuman's active crown branch. @slevis-lmwg also worked on this in #857 so I'm not sure how they are different.

Will do testing, but just pushing this here so @slevis-lmwg and I can coordinate if need be.

Description:

https://github.com/jkshuman/fates/tree/active_crown_Scott_2001
getting the FATES fire module closer to having an active crown fire parameterization.

Collaborators:

@jkshuman @slevis-lmwg

Expectation of Answer Changes:

When a crown fire occurs should change answers

Add EQ to evaluate potential for crown fire
Add EQ for passive crown fire igntion
Set fraction of crown burnt based on this conditional
Add crown fire threshold, crown fire flag, and crown fire PFT param
Following @jkshuman's introduction of the Bessie and Johnson (1995)
formulation for determining the presence of passive crown fire
(NGEET#572),
I now add the same paper's formulation for determining the presence of
active crown fire.

The corresponding issue is NGEET#573

Committing only to get ./manage_externals/checkout_externals to finish
Using existing test:
SMS_Lm12_D_Mmpi-serial.1x1_brazil.I2000Clm50FatesCruRsGs.izumi_intel.clm-FatesFireLightningPopDens
There were two copies of this parameter: a scalar and an array and the
model was getting confused when trying to read them
I found references to both currentCohort%active_crown_fire_flg and
currentPatch%active_crown_fire_flg and I think the latter is correct
and the former incorrect
Calculate required intensity to scorch crown and canopy, then re-calculate
rate of spread and fire intensity

Fixes: 573

User interface changes?: No

Code review:
Fix mistake in equation to solve for phi_wind as part of steps towards calculation of canopy fraction burnt.
