penman_day - Daily ET0 using Penman-Monteith

1	penman_day(vtime, vwind, vtemp, vvpd, vheatflux, altitude = 0)

`vtime`	data frame column or vector containing `date` data
`vwind`	data frame column or vector containing daily wind velocity
`vtemp`	data frame column or vector containing daily temperature
`vvpd`	data frame column or vector containing daily vapor pressure
`vheatflux`	data frame column or vector containing daily total heat flux (latent and sensible heat flux)
`altitude`	study area altitude in meters above sea level

The function returns a data frame with time stamped daily potential evapotranspiration
