Add SSE model type

[barrettk]

Add support for SSE analysis

• A lot of the bootstrap and SSE setup is the same, so this PR refactors bootstrap related functions to related analysis functions. Any change in handling is then defined in the corresponding new_[analysis]_run, setup_[analysis]_run, etc functions.

Example

devtools::load_all()
source("tests/testthat/setup-workflow-ref.R", echo=FALSE)
source("tests/testthat/helpers-create-example-model.R", echo=FALSE)

# New model with MSF saved out
mod2 <- copy_model_from(MOD1, "2") %>% update_model_id()
mod2 <- add_msf_opt(mod2) # helper function from `helpers-create-example-model.R`
submit_model(mod2, .mode = "local")

# Define N number of simulations
N_SIM <- 20

# Simulate data - can also test with mrgsolve
add_simulation(mod2, n = N_SIM, .mode = "local", .overwrite = T)
sim_data <- nm_join_sim(mod2)

# new SSE run
# mod2 <- read_model(file.path(MODEL_DIR, "2"))
sse_run <- new_sse_run(mod2)

sse_run <- setup_sse_run(
  sse_run,
  data = sim_data,
  strat_cols = "SEX",
  n = N_SIM,
  sample_size = 30,
  sim_col = "nn" # IREP for mrgsolve
)

# Print to console to view SSE specifications
sse_run

# Submit and get status
submit_model(sse_run)
get_model_status(sse_run)

# Summarize
summarize_sse_run(sse_run) # I think we need more info here
sse_estimates(sse_run)
