Move 'evidence_epsilon' in 'est_evidence_mcmc'

[richelbilderbeek]

Replace:

create_pir_params <- function(
  # ...
  evidence_epsilon = 1e-12,
  evidence_filename = tempfile(fileext = ".csv")
)

by

create_pir_params <- function(
  # ...
  est_evidence_mcmc = create_nested_sampling_mcmc(),
  # ...
)

which has the same epsilon as a default.

Nonsense, must be part of experiment 😊
