* ICHAIN macros generate an init chain entry of the following form:

* * (e >> 31) & 0x0001 == Continue Parsing after this entry
|

* * (e >> 27) & 0x000F == Type
|
|
* * (e >> 16) & 0x07FF == Offset from start of instance to write initial value
|

* * e & 0xFFFF == Initial Value
|

*
|
|
* Arguments:
|
|
* * type ----- value from enum `InitChainType`
|
|
* * member --- name of member inside `Actor` structure to use as the offset
|
|
* * value ---- s16 value to use
|
|
* * cont ----- ICHAIN_CONTINUE (or ICHAIN_STOP) to continue (or stop) parsing
