Add json_tags_id_camelcase configuration option

[jwc-clinnection]

If json_tags_id_camelcase is true, "ID" in json tags will be camelcase. If false, will be uppercase. Defaults to false

Example where false:

type Example struct {
	ID           uuid.UUID  `json:"id"`
	Name         string     `json:"name"`
	CreatedAt    time.Time  `json:"createdAt"`
	UpdatedAt    time.Time  `json:"updatedAt"`
	CreatedByID  *uuid.UUID `json:"createdByID"`
	UpdatedByID  *uuid.UUID `json:"updatedByID"`
}

Example where true:

type Example struct {
	ID           uuid.UUID  `json:"id"`
	Name         string     `json:"name"`
	CreatedAt    time.Time  `json:"createdAt"`
	UpdatedAt    time.Time  `json:"updatedAt"`
	CreatedByID  *uuid.UUID `json:"createdById"`
	UpdatedByID  *uuid.UUID `json:"updatedById"`
}

I need this so much! Thank you

Discussed this a bit with Andrew, I think we want to go ahead and making a breaking change here. By default, I think we want updated_by_id to map to updatedById. Let's rename the configuration option to be json_tags_id_uppercase and output updatedByID when that's true.

I have pushed the requested changes.
