Renames all idents (variables, types, struct and enum names, fields and constructors) to dispel ambiguities in the target language. Names in reserved, typically keywords and built-ins, will be avoided ; the meaning of the following three flags is described in Bindlib.Renaming.

if namespaced_fields (resp. _constrs) is true, then struct fields (resp. enum constructors) can reuse names from other fields/constructors or other idents.

if prefix_module is true, the qualifying module name is inserted within the ident string, separated with a . dot. This happens before sanitization.

The f_* optional arguments sanitize the different kinds of ids. The default is what is used for OCaml: project to ASCII, capitalise structs, enums (both modules in the backend) and constructors, lowercase fields, and rewrite variables to snake case.

In the returned program, it is safe to directly use `Bindlib.name_of` on variables for printing. The same is true for `StructName.get_info` etc.

val default : t

Basic defaults for minimal renaming, without any reserved keywords, intended for printing intermediate ASTs
