small corrections after v1.0

[donotdespair]

Hey @adamwang15,

I'm looking at our package and we need to improve some things:

• update @references in documentation for estimate.BSVARSIGN
• @adamwang15 I'm looking at the code below

spec$prior$estimate_hyper (mu = TRUE, delta = TRUE, lambda = TRUE, psi = TRUE）

and I think we should make this possible by running

spec$estimate_hyper (mu = TRUE, delta = TRUE, lambda = TRUE, psi = TRUE）

or both should be possible 😸

• Shall we update the example in specify_narrative() so that the current one:

specify_narrative(start = 166, periods = 1, type = "S", sign = 1, shock = 1, var = 6)

was used in context:

narrative = specify_narrative(start = 166, periods = 1, type = "S", sign = 1, shock = 1, var = 6)
specification  = specify_bsvarSIGN$new(monetary, sign_narrative = list(narrative))

• documentation for spec$estimate_hyper a new generic and methods for estimate_hyper() #48
