format.c can already turn an RzType into a pf format string. Add the
inverse in the same file, next to its counterparts:
rz_type_format_to_c_declaration() parses a pf format string with
rz_pf_parse() and emits an equivalent C struct/union declaration built
from the standard fixed-width types (uint8_t, int32_t, float, ...).
The conversion is structural: it consumes only the parsed RzPfFormat
(field kinds, widths, array counts, pointer flags), never a byte buffer,
so it runs without any target data. Every field kind the engine produces
is mapped; a handful of specifiers with no exact static C form are mapped
best-effort (documented inline): @N alignment is dropped, an
unknown-length inline z string becomes char *, LEB128 widens to its
largest decoded integer, and ?(Name) / E(Name) emit struct/enum
references that must themselves be defined to parse.
Added new 'tdf' command that exposes that conversion to the user
