topcompute_fromreg_bilinear_weigaddr interpolation
Return value
weig, addr: 2D arrays, weig and addr are the weight and addresses used to
perform the interpolation:
dataout = total(weig*datain[addr], 1)
dataout = reform(dataout, jpio, jpjo, /over)

Restrictions
- the input grid must be a "regular grid", defined as a grid for which each
lontitudes lines have the same latitude and each latitudes columns have the
same longitude.
- We supposed the data are located on a sphere, with a periodicity along
the longitude.
- points located out of the southern and northern boundaries are interpolated
using a linear interpolation only along the longitudinal direction.
