Handle runs of uppercase letters for name generation

[SebastienGllmt]

Previous handling of uppercase letters in @name generation was not ideal

Notably, @name NFT would result in the generated rust code having functions like new_n_f_t instead of new_nft

This PR should fix this.

Two other things this PR does:

• Fixed the clippy error (doesn't look like it was caused by this PR)
• Adds the missing WASM_BINDGEN_WEAKREF=1 that should be added to the generated package.json

The clippy error wasn't caused by this PR. It was caused from the rust version used on github being upgraded from 1.75 to 1.77. I didn't get it locally (on 1.75) but when I upgraded to 1.77 I did even on master.

I ran the branch on the current spec to see and I noticed for example:

auxiliary_data =
  shelley_format_aux_data ; @name shelley
  / shelley_ma_format_aux_data ; @name Shelley_m_a
  / conway_format_aux_data ; @name conway

which is how it is now produces shelleyma as the variable instead of shelley_ma like I would have expected. I tried changing it to ; @name ShelleyMA and it's the same.

Is this the expected behavior?

Shelley_m_a

I figured out the bug here (it happens even if the name is just m_a

What is happening is that the value passed to convert_to_snake_case is not the comment DSL value as-is. Rather, the label gets converted to camel case first

In both parse_group and create_variants_from_type_choices we do

let variant_ident = VariantIdent::new_custom(convert_to_camel_case(&ident_name));
EnumVariant::new(variant_ident, ty, serialize_as_embedded)

so if you start with m_a

• convert_to_camel_case("m_a") → MA
• convert_to_snake_case("MA") → ma (with this new PR)

not sure what is the best way to solve this in the code without making a mess of everything

@SebastienGllmt I updated this and fixed the issues we had with things like shelley_ma, etc. The general approach seems to be to either do ShelleyMA or for general cddl consistency/similarity to our usual cddl defs from IOHK shelley_MA (snake case everywhere but runs of uppercases are recommended to be in all-caps e.g. IP_address, VRF_vkey, etc)
