Given a space-time-lagged neighbor list and a weights lists, e.g. made by
`st_dist_band()`

or `st_contiguity()`

, create a corresponding weights list.

## Arguments

- wt
a weights lists created from a spacetime object's geometry context.

- nbt
a time-lagged spatial neighbors list created by

`spt_nb()`

- n_times
the number of time slices

- n_locs
the number of locations

## Details

It is intended that `spt_wt()`

is used following the use of `spt_nb()`

using the same input arguments. This ensures that the time-lagged spatial
weights are correctly associated with the time-lagged spatial neighbors.

`spt_nb()`

for creating spacetime neighbors which are inputs into spacetime weights
