feat: add AnyNetwork

[leruaa]

Closes #81

[onbjerg]

please also remove the catch all fields currently present on some of the rpc-types, e.g.

alloy/crates/rpc-types/src/eth/block.rs

Lines 962 to 963 in 28cab90

	#[serde(flatten)]
	pub extra_info: BTreeMap<String, serde_json::Value>,

alloy/crates/rpc-types/src/eth/transaction/request.rs

Lines 55 to 57 in 28cab90

	/// Support for arbitrary additional fields.
	#[serde(flatten)]
	pub other: OtherFields,

alloy/crates/rpc-types/src/eth/transaction/receipt.rs

Lines 56 to 58 in 28cab90

	/// Arbitrary extra fields.
	#[serde(flatten)]
	pub other: OtherFields,

[leruaa]

Not sure if this should be removed:

alloy/crates/rpc-types/src/eth/block.rs

Lines 962 to 963 in 28cab90

	#[serde(flatten)]
	pub extra_info: BTreeMap<String, serde_json::Value>,

as Block is not part of Network types.

Edit: Looks like Block should be added as a Network type, as mentioned in #267. Maybe I can take that issue as a follow up, and take this into account at that moment?

[onbjerg]

@leruaa Makes sense, pls flag in that issue that we need to make the proper adjustments it for AnyNetwork

Approving, with a followup issue to add tests with various networks' receipt types in #424

The PR shows a requested change from @mattsse, but I marked all conversations as resolved. Is this a bug?

[prestwich]
