This PR adds LA 100-P information to AMDS/current card section in AMDC article to close #155.

Notes

Here is the note from a previous student of how to determine the burden resister:

For the current card, the burden voltage was chosen as 10V by the card designer so that it is within the range of the Analog to Digital Converter.
If you choose anything lower than 10V, that should be okay.

I see your concern that the datasheet recommends the burden resistor to be 0-33 ohms. So in your case the burden voltage will be lower than 10V
For a current range of 150V, your secondary current will be I_secondary = 150/2000 = 0.075A.
(V_burden = R*I_secondary = 33*0.075 = 2.475V)

For my card designs I think that I had chosen 28 Ohms

@Daehoon-Sung when you have a chance, could you review the updated current card article of AMDC doc? Here is the rendered article: Current - AMDC Platform.pdf

I added a new sensor information of LA 100-P:

Datasheet can be found in this PR that we are planning to merge soon as well. Also, I am wondering if we want to do the same calculation using the LA 100-P as follows:

Do you have any ideas of how we can achieve sensing of Vout = 0V @-150 A and Vout = 5V @150 A using the LA 100-P sensor?
