Bug fix for building height in LCZ urban parameter table

TYPE: bug fix

KEYWORDS: urban, BEP, BEP_BEM, parameter table, building height

SOURCE: Cenlin He (NCAR), Alberto Martilli (CIEMAT, Spain)

DESCRIPTION OF CHANGES:
Problem:
The BEP and BEP_BEM urban schemes (urban_physics = 2,3) require the building height distribution to be a multiple of 5-m because of the hard-coded dz_u = 5 parameter in BEP and BEP_BEM source code. However, currently the urban parameter table (URBPARM_LCZ.TBL) has a building height distribution as a multiple of 3-m, which will cause model issues.

Solution:
Change the building height distribution in URBPARM_LCZ.TBL to be a multiple of 5-m. In addition to the model code requirement as mentioned above, the justifications of this change also include: (1) the NUDAPT database has building heights as a multiple of 5m. (2) the updated mean building heights in URBPARM_LCZ.TBL aer equal to the middle range values of the urban LCZs from Stewart and Oke (2012): Stewart, I. D., & Oke, T. R. (2012). Local climate zones for urban temperature studies. Bulletin of the American Meteorological Society, 93(12), 1879-1900.
