feat(p/json): optimize json

[notJoon]

Description

Optimized the JSON package and simplified JSON node creation using the builder pattern.

• in buffer.gno and escape.gno files are modified the use of map for lookup tables to use slice array instead.
• refactor the Unquote function in escape.gno file
• modified the existing functions that parsed numbers to use strconv package, and deleted related files and functions
  • especially, the eisel_lemire and ryu packages were deleted since they were files that had been added to handle ParseUint and ParseFloat in strconv package.

JSON Generate Example

Plain JSON

node := Builder().
	WithString("name", "Alice").
	WithNumber("age", 30).
	WithBool("is_student", false).
	Node()

value, err := Marshal(node)
if err != nil {
	t.Errorf("unexpected error: %s", err)
}

Output:
{"name":"Alice","age":30,"is_student":false}

Nested Structure

node := Builder().
	WriteString("name", "Alice").
	WriteObject("address", func(b *NodeBuilder) {
		b.WriteString("city", "New York").
		WriteNumber("zipcode", 10001)
	}).
	Node()
// ...

Output:
{"name":"Alice","address":{"city":"New York","zipcode":10001}}
