### Description
As hex values can include letters `A` through to `F`, certain English words can be spelled out, such as `CAFE`, `BEEF`, or `FACADE`.
This vocabulary can be extended by using numbers to represent other letters, such as `5EAF00D`, or `DEC0DE5`.

Given a string, your task is to return the decimal sum of all words in the string that can be interpreted as such hex values.


### Example

Working with the string `BAG OF BEES`:  
* `BAG` ==> `0` as it is not a valid hex value  
* `OF` ==> `0F` ==> `15`  
* `BEES` ==> `BEE5` ==> `48869`

So `hex_word_sum('BAG OF BEES')` returns the sum of these, `48884`.


### Notes
* Inputs are all uppercase and contain no punctuation
* `0` can be substituted for `O`
* `5` can be substituted for `S`
