Replace JsValue::into/from_serde with serde-wasm-bindgen

[sergeyboyko0791]

wasm-bindgen::serde-serialize feature may lead to a cyclic package dependency like

error: cyclic package dependency: package `wasm-bindgen v0.2.74` depends on itself. Cycle:
package `wasm-bindgen v0.2.74`
    ... which is depended on by `js-sys v0.3.51`
    ... which is depended on by `getrandom v0.2.2`
    ... which is depended on by `ahash v0.7.4`

Due to this problem, JsValue::into_serde and JsValue::from_serde were deprecated at rustwasm/wasm-bindgen#3031

serde-wasm-bindgen likely doesn't handle serde(deny_unknown_fields) attribute properly. Will try to find a workaround.

[sergeyboyko0791]

I had to disable serde(deny_unknown_fields) due to RReverser/serde-wasm-bindgen#39

[sergeyboyko0791]

As a workaround I can follow this advice RReverser/serde-wasm-bindgen#39 (comment)
Please let me know if it's critical to deny unknown fields.

deny_unknown_fields was kind of inherited from jsonrpc_core while solving #544.
I like it, but for no particular practical reason, just an ocd. But getting rid of a deprecation warning is way more important, so thank you for the PR!
