Create a fixed effect incidence matrix

Creates an incidence matrix for the fixed effects of a mixed-model. This is a very thin wrapper around stats.

fixef_model_matrix(fixed, data, sparse = TRUE)

`fixed`	A `formula` specifying the the response variable and the fixed effect terms of the linear mixed-model. Must take the form `response ~ predictor(s)`.
`data`	A `data.frame` that includes the response and fixed effect predictors. If not supplied, the function will look in the current running environment.
