Move casing utils to tn-utils instead of having them in tn-models library

[lakardion]

We currently have these function utils being used internally in the library but they were developed because the ones that tn-utils had available were not working properly for our use case.

tn-models-fp/src/utils/api/api.ts

Lines 20 to 40 in a9a123d

	//TODO: this should probably move to tn-utils but will keep it here for a quick release
	export const objectToCamelCaseArr = <T extends object>(obj: T): CamelCasedPropertiesDeep<T> => {
	if (typeof obj !== "object" || obj === null) return obj
	if (Array.isArray(obj)) return obj.map((o) => objectToCamelCaseArr(o)) as CamelCasedPropertiesDeep<T>
	const entries = Object.entries(obj)
	const newEntries = []
	for (const [k, v] of entries) {
	newEntries.push([toCamelCase(k), objectToCamelCaseArr(v)])
	}
	return Object.fromEntries(newEntries)
	}
	export const objectToSnakeCaseArr = <T extends object>(obj: T): SnakeCasedPropertiesDeep<T> => {
	if (typeof obj !== "object" || obj === null) return obj
	if (Array.isArray(obj)) return obj.map((o) => objectToSnakeCaseArr(o)) as SnakeCasedPropertiesDeep<T>
	const entries = Object.entries(obj)

	for (const [k, v] of entries) {
	newEntries.push([toSnakeCase(k), objectToSnakeCaseArr(v)])
	}
	return Object.fromEntries(newEntries)
	}
