The current output format for the `xx_bit_size` is `symbol-name:size`.
```
{Struct} 'struct_bitfield'
  {Member} public 'code' -> 'int'
  {Member} public 'debug':1 -> 'int'
  {Member} public 'release':2 -> 'int'
```
How do you feel if we follow a similar approach for the `xx_byte_size`
```
{BaseType} 'bool:1'
{BaseType} 'int:4'
{BaseType} 'unsigned int:4'
```
