Describe the bug
@JsonFormat does not work as expected when converting string to double and vice versa.

Version information
2.11.3

To Reproduce
I have an entity with a double property. Challenge is to read an external API that sends the capacity value as string in German Format.

@JsonIgnoreProperties(ignoreUnknown = true)
data class Event(
		@JsonProperty("NUMCap

Jsoniter project (https://github.com/plokhotnyuk/jsoniter-scala) has many impressive performance optimizations; linked f.ex from here:

https://www.reddit.com/r/java/comments/darehu/jackson_release_210/f1ysf1e/

Of ones included, number-parsing would be relevant for this repo.

EDIT: also see (from the comment below)

"Unrelated to jsoniter but this recent port of Lemire's Double parser:

Hi there, thanks for this project. Very happy so far.

We're trying to migrate to scala 3, and on of the things which came up was this.

I need to make this manual change to use a generated http4s client, in Implicits.scala

-    implicit val showString = build[String](Predef.identity)
-    implicit val showInt = build[Int](_.toString)
-    implicit val showLong = build[Long](_.

Tools like jq are focused predominantly on their use on the command line, but have a lot of limitations (and bugs!) that jslt doesn't. This is a compliment to jslt btw. :)

To properly replace the usage of jq with jslt, we would like to be able to have some more flexibility with the ways of specifying the input parameters as well as the output.

• Specifying JSON input or JSLT transform input

InstantSerializer doesn't respect any of the following standard Jackson configuration settings:

ObjectMapper#setDateFormat
@JsonFormat(pattern) on an Instant
others?

Instead, I have to create and manually override the default InstantSerializer registered by the module.

This isn't well documented and is definitely confusing when using the library.
Can we make InstantSerializer

It would be nice to have a CSV feature similar to JSON feature JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS. Enabling of the feature by mapper.enable(JsonGenerator.Feature.WRITE_NUMBERS_AS_STRINGS) doesn't work for CSV.

I want to write an object of this class:

data class TestData(
        val integer: Int,
        val float: Float
}

as
"1","1.234"
not as
1,1.234
