Generate the simulations of the expert_matrix

sim_dataset(
  alpha,
  x,
  expert_matrix = NULL,
  comp_dist,
  params_list,
  exposure = rep(1, dim(x)[1])
)

`alpha`	(`matrix`) A g * P matrix. Logit regression coefficients.
`x`	(`matrix`) An N * P covariate matrix, where N is sample size. The first column MUST be 1 for an intercept term.
`expert_matrix`	(`ExpertMatrix`) A D*g expert matrix.
`comp_dist`	(`matrix`) A D * g string matrix, representing the name of expert functions.
`params_list`	(`matrix`) A D * g matrix of lists, representing the parameters of expert functions.
`exposure`	A N*1 vector that contain the exposure value for each column in expert_matrix

A N*D simulation matrix of expert_matrix.
